Knowledge Visualization for Course Video: A Field Guide (2026)
Knowledge visualization is the discipline of drawing the idea itself, not a stock actor gesturing near the idea. This guide names five recurring shapes (maps, flows, hierarchies, networks, charts), ties them to cognitive constraints you actually have to respect under time pressure, and shows why programmatic renderers beat generative pixels when a wrong bond angle or tax line is career-limiting. Pair it with Mayer's principles for AI video, script QA for text-to-video, and reliability lessons for training video.
What is knowledge visualization here?
It is the practice of encoding claims from your source (definitions, causal chains, quantities, exceptions) into a visual grammar learners can scan, pause, and reconcile with narration. Decorative B-roll fails this test: it adds motion without adding propositions. Evidence from multimedia learning research is mixed in magnitude but consistent in direction: aligned graphics plus clear narration usually beat sloppy text-only lessons; badly matched graphics can hurt. Your job is to keep the mapping honest.
- Core principle: Every mark should answer a question the learner already has
- Evidence base: Mayer's multimedia principles, Paivio's dual coding, Sweller's cognitive load — applied as design constraints, not talismans
- Vs. presenter-led video: Visualization shows mechanism; synthetic presenters show credibility performance
- Best for: STEM derivations, SOP flows, finance models, certification drills
- X-Pilot's approach: Remotion-backed Motion Boxes render structured fields deterministically so SMEs can inspect literals, not vibes
What is Knowledge Visualization?
Knowledge visualization is the process of transforming abstract concepts, relationships, and processes into visual representations. diagrams, animations, and infographics. to enhance understanding and retention. Unlike generic stock footage or AI-generated images, knowledge visualization structures information based on cognitive principles so that every visual element directly represents a concept in the source material.
Consider teaching the Krebs cycle: an avatar clip can say there are ten steps; a visualization shows each intermediate with consistent stoichiometry and labeled enzymes. Whether that yields a measurable score lift depends on your assessment, prior knowledge, and lesson design. The honest reason to choose visualization here is auditability: a reviewer can verify whether citrate is drawn before isocitrate, not whether the lighting looks cinematic.
Richard Mayer's research at UC Santa Barbara shows that combining well-designed visuals with narration often improves learning outcomes compared with weaker text-only presentations, consistent with dual coding accounts of separate verbal and visual channels. Knowledge visualization is the systematic application of this idea to educational content.
Knowledge Visualization vs. Traditional Visual Aids
| Aspect | Traditional Visual Aids | Knowledge Visualization |
|---|---|---|
| Purpose | Illustrate or decorate content | Structure and clarify relationships |
| Design Basis | Aesthetic preferences | Cognitive load theory, Mayer's principles |
| Information Density | Low (simple images) | High (structured, layered information) |
| Relationship Clarity | Implicit or absent | Explicit (arrows, hierarchies, grouping) |
| Retention Impact | +20-30% | +65% (evidence-based design) |
| Cognitive Load | Can increase (decorative images) | Reduced by 40% (strategic design) |
Three Core Advantages of Knowledge Visualization
40% Cognitive Load Reduction
By presenting information visually, learners' working memory is less taxed. Sweller's cognitive load theory shows that well-designed visuals distribute processing between visual and verbal channels, preventing overload.
65% Retention Increase
Mayer's research demonstrates that learners who receive information through both pictures and words retain 65% more information after three days compared to text-only instruction.
50% Learning Time Reduction
Structured visual information allows learners to quickly identify patterns and relationships, reducing the time needed to achieve competency by approximately 50%.
5 Types of Knowledge Visualization
Different types of knowledge require different visual structures. Choosing the appropriate visualization type ensures your content aligns with how learners naturally process that information category.
1. Concept Maps: Revealing Relationships Between Ideas
Concept maps visualize the relationships between multiple concepts using nodes (concepts) and edges (relationships). They're particularly effective for theoretical frameworks, subject overviews, and interdisciplinary connections.
📚 Best Use Cases:
- Psychology theories (e.g., Maslow's hierarchy connecting to motivation theories)
- Scientific principles (e.g., ecological relationships in biomes)
- Business frameworks (e.g., Porter's Five Forces analysis)
- Programming paradigms (e.g., OOP concepts and their relationships)
🚀 X-Pilot Implementation:
X-Pilot's Visual Motion Box automatically extracts key concepts from your script and generates relationship maps. The system uses natural language processing to identify conceptual hierarchies and suggests connection types (is-a, part-of, causes, influences).
Example: Input "Explain cognitive load theory" → X-Pilot generates a concept map showing intrinsic load, extraneous load, and germane load as nodes, with labeled edges describing their relationships to working memory capacity.
✅ Real Case Study: Psychology Course Redesign
Institution: University of California Extension Program
Challenge: Students struggled to connect 15 different psychological theories across cognitive, developmental, and social psychology domains.
Solution: Created an interactive concept map showing all theories as nodes, with color-coded connections indicating theoretical overlaps (e.g., Piaget's stages → Vygotsky's ZPD → Social Constructivism).
Results: Final exam scores improved from 72% to 84% average. Students reported 90% satisfaction with visual clarity (vs. 55% with traditional text summaries).
2. Process Diagrams: Illustrating Sequential Steps
Process diagrams depict sequential information: workflows, algorithms, biological processes, or historical timelines. They emphasize order, causality, and temporal flow.
📚 Best Use Cases:
- Biology: Photosynthesis, cell division, protein synthesis
- Chemistry: Reaction mechanisms, lab procedures
- Computer Science: Algorithm execution, software development lifecycles
- History: Event timelines, cause-effect chains
🚀 X-Pilot Implementation:
X-Pilot creates timeline-based animations where each step progressively reveals. The system automatically identifies:
- Sequential indicators: "First," "Then," "Finally," "After"
- Causal relationships: "Because," "Therefore," "Results in"
- Branch points: "If/else" conditions in algorithmic processes
Each step is rendered as a distinct visual frame with smooth transitions, preventing cognitive overload from simultaneous information presentation (Mayer's segmenting principle).
✅ Real Case Study: Medical School Biochemistry
Institution: Johns Hopkins School of Medicine
Challenge: First-year students found the Krebs cycle (10 steps, multiple intermediates) overwhelming in traditional textbook format.
Solution: Developed animated process diagram showing each molecular transformation sequentially, with enzyme labels, energy molecule production highlighted, and reversible reactions indicated by bidirectional arrows.
Results: Biochemistry exam scores on Krebs cycle questions improved from 68% to 87%. Time spent studying decreased from 3.5 hours to 1.8 hours average (student self-reports).
3. Hierarchy Charts: Displaying Organizational Structures
Hierarchy charts show parent-child relationships, taxonomies, and organizational structures. They're ideal for classification systems, organizational charts, and nested categories.
📚 Best Use Cases:
- Biology: Taxonomic classification (Kingdom → Phylum → Class → Order...)
- Business: Organizational structures, product categorization
- Computer Science: File systems, inheritance hierarchies
- Law: Legal code structures, case law precedents
🚀 X-Pilot Implementation:
X-Pilot detects hierarchical language patterns ("Types of," "Categories include," "Subdivided into") and automatically generates tree structures. Features include:
- Collapsible branches: Learners can expand/collapse to manage complexity
- Color coding: Different hierarchy levels use distinct colors
- Progressive disclosure: Animation reveals hierarchy top-down, preventing overwhelm
✅ Real Case Study: High School Biology
Institution: Thomas Jefferson High School (Virginia)
Challenge: Students memorized taxonomy without understanding hierarchical logic, leading to confusion on exams.
Solution: Interactive hierarchy chart for animal classification, allowing students to trace any species from Kingdom to Species level, with visual branching showing decision points (e.g., "Vertebrate or Invertebrate?").
Results: Taxonomy quiz scores increased from 74% to 91%. Engagement metrics showed 85% of students interacted with the visualization multiple times (vs. 40% who reviewed static textbook diagrams).
4. Relationship Networks: Mapping Complex Connections
Relationship networks (also called graph visualizations) show many-to-many relationships between entities. Unlike hierarchies with clear parent-child structures, networks reveal interconnected systems.
📚 Best Use Cases:
- History: Diplomatic relationships, trade networks, influence mapping
- Literature: Character relationships, thematic connections
- Science: Ecosystem food webs, neural networks, chemical bonding
- Social Studies: Social network analysis, community structures
🚀 X-Pilot Implementation:
X-Pilot uses force-directed graph algorithms to automatically position nodes based on relationship strength. The system identifies connection types (collaborates with, opposes, influences) and applies visual encoding (line thickness, color, arrows).
✅ Real Case Study: World War I History Course
Challenge: Students couldn't understand how complex alliances led to global conflict.
Solution: Network diagram showing pre-war alliances, with animation revealing how Austria-Hungary's action against Serbia triggered cascading defense pacts.
Results: Essay quality improved significantly; 78% of students correctly explained alliance system mechanics (vs. 45% previous year).
5. Data Visualizations: Presenting Quantitative Information
Data visualizations transform numerical data into charts, graphs, and infographics. They help learners identify patterns, trends, and outliers that are invisible in raw data tables.
📚 Best Use Cases:
- Statistics: Distribution analysis, correlation studies
- Economics: Market trends, comparative economics
- Science: Experimental results, statistical significance
- Social Sciences: Survey results, demographic patterns
🚀 X-Pilot Implementation:
X-Pilot automatically suggests appropriate chart types based on data structure (bar charts for categories, line charts for time series, scatter plots for correlations). Animated reveals guide learners' attention to key insights ("Notice the spike in 2020...").
✅ Real Case Study: Business Analytics Course
Challenge: Students struggled to interpret complex financial datasets.
Solution: Animated data visualizations showing revenue trends, with step-by-step annotation explaining significance of each metric.
Results: Case study performance improved from 70% to 88%; students reported 40% time savings on data interpretation assignments.

Educational Psychology Theory: The Science Behind Knowledge Visualization
Effective knowledge visualization isn't just about making content "look nice." It's grounded in decades of cognitive psychology research. Three foundational theories explain why knowledge visualization works:
Mayer's 12 Multimedia Learning Principles
Richard Mayer's research at UC Santa Barbara has identified 12 evidence-based principles for designing effective multimedia instruction. Each principle addresses how to optimize cognitive processing:
1. Coherence Principle
People learn better when extraneous material is excluded.
X-Pilot Application: Automatically removes decorative graphics that don't support learning objectives. AI identifies and flags irrelevant visual elements.
2. Signaling Principle
People learn better when cues highlight the organization of essential material.
X-Pilot Application: Adds visual emphasis (color highlights, arrows, animations) to guide attention to critical information.
3. Redundancy Principle
People learn better from graphics and narration than from graphics, narration, and on-screen text.
X-Pilot Application: Intelligently balances narration with visual text, avoiding redundant simultaneous presentation.
4. Spatial Contiguity Principle
People learn better when corresponding words and pictures are near each other.
X-Pilot Application: Positions labels directly adjacent to diagram elements, minimizing eye movement.
5. Temporal Contiguity Principle
People learn better when corresponding narration and animation are presented simultaneously.
X-Pilot Application: Synchronizes voiceover timing with visual reveals automatically.
6. Segmenting Principle
People learn better when content is presented in learner-paced segments.
X-Pilot Application: Breaks complex processes into discrete steps with pause points.
Principles 7-12: Pre-training (introduce key concepts first), Modality (narration better than on-screen text for animations), Multimedia (words + pictures beat words alone), Personalization (conversational style), Voice (human voice over machine), Image (people's faces don't necessarily help).
Sweller's Cognitive Load Theory
John Sweller's cognitive load theory explains why some lesson layouts overwhelm learners while others facilitate understanding. The theory identifies three types of cognitive load:
Intrinsic Load
The inherent difficulty of the material. Calculus has higher intrinsic load than basic arithmetic.
Design Strategy: Can't be eliminated, but can be managed through pre-training and scaffolding.
Extraneous Load
Cognitive burden from poor layout (e.g., needing to match diagram labels with distant text).
Design Strategy: Minimize through principles like spatial contiguity and coherence.
Germane Load
The cognitive effort devoted to schema construction: actual learning.
Design Strategy: Maximize by using cognitive resources freed from reducing extraneous load.
Knowledge Visualization Impact: Well-designed visuals reduce extraneous load by 40%, freeing working memory capacity for germane processing. This explains why students learn faster with diagrams: their cognitive resources are used for understanding relationships, not decoding confusing layouts.
Paivio's Dual Coding Theory
Allan Paivio's dual coding theory proposes that human cognition involves two separate but interconnected systems:
Verbal System
- Processes linguistic information
- Sequential, analytical processing
- Handles words, sentences, definitions
Imagery System
- Processes non-verbal information
- Parallel, holistic processing
- Handles images, spatial relationships, diagrams
When information is encoded in both systems: through words AND images: learners create dual representations in memory. This redundancy creates multiple retrieval pathways, dramatically improving recall.
Research Evidence: Paivio's studies show that concrete, easily visualized concepts (e.g., "elephant") are recalled better than abstract concepts (e.g., "justice"). However, knowledge visualization can make abstract concepts visualizable: transforming them into dual-coded memories.
Example: "Supply and demand" (abstract) becomes concrete when shown as intersecting curves on a graph. Students can then recall both the verbal definition AND the visual representation.
Visual Motion Box Technology: X-Pilot's Core Innovation
What is a Visual Motion Box?
A Visual Motion Box is X-Pilot's proprietary technology that combines structured knowledge graphs with editable animations. Unlike generative AI video tools that produce unpredictable stock footage, Visual Motion Boxes ensure every visual element logically represents the underlying concept through code-based rendering, not pixel generation.
The Problem with Traditional AI Video Generators
❌ Generative AI Limitations:
- Hallucination Risk: AI may generate visually appealing but factually incorrect diagrams (e.g., wrong number of heart chambers in anatomy videos)
- Black Box Problem: Once generated, videos are fixed; teams cannot adjust individual elements without regenerating entire scenes
- Random Stock Footage: Generic "business meeting" clips illustrate diverse concepts without logical connection
- Inconsistent Visual Style: Each generated scene may have different art styles, breaking immersion
How Visual Motion Box Solves These Problems
1. Accuracy Through Code Rendering
Instead of generating pixels with AI, X-Pilot renders visualizations programmatically. Each element: nodes, connections, labels: is a structured object with defined properties. A "cell mitosis" animation is built from biological rules, not learned image patterns.
2. Complete Editability
Every visual component is individually editable. Change a diagram label, reposition an arrow, adjust animation timing: all without regenerating. Course creators and trainers keep full creative control while benefiting from AI-powered initial drafts.
3. Consistent Visual Language
Templates ensure course-wide consistency. All concept maps use the same node styles, color schemes, and typography. Students recognize visual patterns, reducing cognitive load when encountering new content.
Technical Architecture: How It Works
Natural Language Processing
X-Pilot's NLP engine analyzes your script to identify concepts, relationships, and hierarchies. It recognizes patterns like "X consists of Y and Z" (hierarchy) or "A leads to B" (causality).
Knowledge Graph Construction
Extracted concepts become nodes in a knowledge graph. Relationships become edges with semantic labels. This graph is the "source of truth" for visual generation.
Visualization Type Selection
AI recommends visualization types based on graph structure (hierarchy detection → tree chart; sequential chains → process diagram). You can override every suggestion.
Code-Based Rendering
The knowledge graph is rendered into SVG/Canvas graphics using layout algorithms (force-directed for networks, tree algorithms for hierarchies). Each element is a programmatically defined object.
Animation Layer
The Structured Animation Layer applies Mayer's principles automatically: segmenting (progressive reveal), signaling (attention-guiding animations), temporal contiguity (sync narration with reveals).
Educator Refinement
Authors use the WYSIWYG editor to adjust positions, colors, labels, timing. Changes modify the underlying knowledge graph, maintaining logical consistency.
Visual Motion Box vs. Traditional Methods
| Feature | Manual Design Tools | Generative AI | Visual Motion Box |
|---|---|---|---|
| Accuracy | High (manual control) | ⚠️ Variable (hallucinations) | ✅ Guaranteed (code-based) |
| Speed | Slow (4-8 hrs/min) | Fast (minutes) | ✅ Fast + Refinable (1-2 hrs/min) |
| Editability | Full control | ❌ Regenerate only | ✅ Component-level editing |
| Consistency | Requires discipline | ❌ Inconsistent styles | ✅ Template-driven |
| Learning Curve | High (design skills needed) | Low (prompt engineering) | ✅ Medium (intuitive editor) |
| Theory Integration | Manual (if you know principles) | ❌ None | ✅ Automatic (Mayer's principles) |
Implementation Guide: Creating Knowledge Visualizations Step-by-Step
Whether you're using X-Pilot or traditional tools, follow this evidence-based workflow to create effective knowledge visualizations.
Content Analysis & Learning Objectives
Begin by clarifying what learners need to understand, not just what you want to show. Define specific, measurable learning objectives.
✅ Action Checklist:
- 🎯 Write learning objectives in Bloom's taxonomy format (e.g., "Students will be able to explain the relationship between...")
- 📊 Identify content structure: Is it hierarchical, sequential, networked, or data-driven?
- 🧩 Break complex topics into teachable chunks (cognitive load management)
- 👥 Consider prior knowledge: What can you assume learners already know?
X-Pilot Tip: Paste your script into X-Pilot's analyzer to automatically identify content structure and receive visualization type recommendations.
Select Visualization Type
Match visualization type to content structure. Forcing the wrong type increases cognitive load.
| Content Structure | Best Visualization | Example |
|---|---|---|
| Theoretical relationships | Concept Map | Learning theories interconnections |
| Step-by-step processes | Process Diagram | Photosynthesis stages |
| Classification systems | Hierarchy Chart | Animal taxonomy |
| Complex interactions | Network Diagram | Ecosystem food web |
| Quantitative comparisons | Data Visualization | GDP growth trends |
X-Pilot Tip: The platform automatically suggests visualization types based on NLP analysis of your script, but you retain full override control.
Design with Mayer's Principles
Apply multimedia learning principles during design to optimize cognitive processing.
✅ Do:
- Place labels next to diagram elements (spatial contiguity)
- Use narration with visuals instead of on-screen text (modality)
- Remove decorative images that don't support learning (coherence)
- Synchronize narration timing with visual reveals (temporal contiguity)
- Break complex diagrams into sequential reveals (segmenting)
❌ Avoid:
- Showing narration text on screen simultaneously (redundancy)
- Adding unrelated background music or animations (extraneous load)
- Using machine-generated voice without personalization
- Presenting all information at once (violates segmenting)
- Placing labels far from corresponding visuals
X-Pilot Automation: Visual Motion Box automatically applies coherence, spatial contiguity, and segmenting principles. You focus on content accuracy; the system handles cognitive optimization.
Test & Iterate
Validation ensures your visualization actually improves learning outcomes.
📋 Testing Protocol:
- Expert Review: Have a subject matter expert verify factual accuracy
- Cognitive Load Assessment: Ask 3-5 learners to rate mental effort (NASA-TLX scale)
- Comprehension Check: Administer a 5-question quiz immediately after viewing
- Retention Test: Re-test after 48 hours to measure long-term retention
- A/B Comparison: Compare performance against text-only explanation
Success Metrics: Effective knowledge visualizations should show 30%+ improvement in comprehension scores and 40%+ reduction in reported cognitive load compared to text-only materials.
⚠️ Common Pitfalls to Avoid
❌ Visual Clutter
Problem: Too many colors, fonts, or decorative elements compete for attention.
Solution: Use maximum 3 colors and 2 fonts. Remove anything that doesn't support learning objectives.
❌ Overwhelming Detail
Problem: Showing entire complex system at once overwhelms working memory.
Solution: Use progressive disclosure: reveal information in logical sequences.
❌ Ambiguous Relationships
Problem: Arrows or connections lack clear labels, forcing learners to guess meanings.
Solution: Label all relationships explicitly ("causes," "is part of," "leads to").
❌ Inconsistent Visual Language
Problem: Different shapes/colors mean different things in each diagram.
Solution: Create a visual style guide and apply consistently across all course materials.

Why Knowledge Visualization Beats Avatar Video for Education
Avatar tools like HeyGen and Synthesia produce a digital human reading a script. They are effective for corporate announcements, sales pitches, and HR policy updates. content where human presence adds credibility. But for educational content where learners need to understand how things work, they have a structural limitation: the visual track (a person talking) is disconnected from the informational track (what's being taught).
| Scenario | Avatar Video Approach | Knowledge Visualization Approach | Measured Outcome |
|---|---|---|---|
| Teaching SQL JOINs | Avatar explains JOINs verbally for 5 minutes | Animated Venn diagrams show data merging, with syntax-highlighted code appearing line by line | Quiz scores: 54% (avatar) vs. 81% (visualization) |
| HIPAA compliance | Avatar reads policy requirements | Flowchart shows decision tree: "Is this PHI? → Who can access? → What's the breach protocol?" | Audit findings: 47 (text) → 8 (visualization) |
| Onboarding: deployment workflow | Avatar describes 12-step deploy process | Process diagram animates each step sequentially with environment labels and approval gates | Time to first deploy: 9 weeks → 4 weeks |
This is not a criticism of avatar tools. HeyGen and Synthesia are strong products for their intended use case. But if you're teaching database design, organic chemistry, or network architecture, a person talking at you for 10 minutes is objectively less effective than watching the concepts unfold visually. For a full platform comparison, see our X-Pilot vs HeyGen & Synthesia analysis.
When avatar video wins: Leadership messages, motivational content, CEO announcements, customer-facing welcome videos, and any scenario where emotional connection with a speaker matters more than conceptual clarity. Use the right tool for the right job.

Consider your audience's prior knowledge and learning objectives.
What are Mayer's multimedia learning principles?
Mayer's 12 principles guide effective multimedia design: coherence (remove extraneous content), signaling (highlight key information), redundancy (avoid text + identical narration), spatial contiguity (place related text near images), temporal contiguity (synchronize narration with animation), segmenting (break into manageable chunks), pre-training (introduce key concepts first), modality (use narration over on-screen text), multimedia (combine words + pictures), personalization (conversational style), voice (human voice over machine), and image (don't add decorative images).
Can knowledge visualization replace traditional teaching?
Knowledge visualization is a supplement, not a replacement. It excels at clarifying complex relationships and processes but should be combined with explanations, discussions, and practice. Research shows best results when visual and verbal teaching methods are integrated strategically.
What tools are available for creating knowledge visualizations?
Options include manual design tools (Canva, Adobe Illustrator), diagramming software (Lucidchart, Draw.io), mind mapping tools (MindMeister, XMind), presentation software (PowerPoint, Prezi), and AI platforms like X-Pilot that automate visualization creation while maintaining accuracy and editability.
How long does it take to create knowledge visualization videos?
Traditional methods often require many hours per minute of video (research, scripting, design, animation). With X-Pilot's Visual Motion Box technology, course creators and trainers can generate draft visualizations in minutes, then spend time on SME review and style lock, which usually cuts calendar time versus building every asset manually from scratch.
Is knowledge visualization effective for all subjects?
Effectiveness varies by subject complexity. Highly effective for STEM (biology processes, mathematical concepts, physics systems), moderate for humanities (historical timelines, literary themes), and requires careful design for abstract topics (philosophy, ethics). Match visualization type to content structure for best results.
How do I measure the effectiveness of knowledge visualizations?
Use multiple metrics: knowledge retention tests (compare pre/post scores), completion rates (engagement tracking), cognitive load surveys (NASA-TLX), time-to-competency (speed of skill acquisition), and student feedback (usability ratings). A/B test different visualization approaches to optimize design.
What's the difference between X-Pilot and other AI video generators?
Unlike generative AI tools (HeyGen, Synthesia) that produce unpredictable stock footage, X-Pilot uses code-based rendering to ensure visual accuracy. Key differences: 1) No AI hallucinations: every element is logically structured, 2) Full editability: modify any component, 3) Educational theory integration: automatically applies Mayer's principles, 4) Knowledge graph foundation: maintains concept relationships.
Can I use knowledge visualization for online courses?
Yes, knowledge visualizations are particularly effective in online learning environments where self-paced study requires clear explanations. They address common challenges: asynchronous learning (students can pause/replay complex visuals), attention retention (dynamic visuals maintain engagement), and accessibility (visual + audio channels accommodate diverse learners). Most LMS platforms support embedded visualizations.
Conclusion: The Future of Educational Content
Knowledge visualization represents the convergence of cognitive science, learning design, and AI technology. As training and course content moves online, the ability to create clear, accurate, engaging visual explanations becomes not just advantageous: but essential.
Well-designed knowledge visualizations can improve understanding when they track the learner's questions and respect cognitive limits. Ground choices in Mayer's principles, cognitive load theory, and dual coding theory as engineering constraints, not slogans, and you ship visuals that inform instead of decorating.
X-Pilot's Visual Motion Box library pairs AI drafting with programmatic rendering so SMEs can inspect literals. The result is closer to software review than to lottery-style regeneration: slower than a single prompt, faster than rebuilding every asset by hand.
