**Key Enhancement:** Each iteration fetches a web URL, learns specific techniques, and applies them to create progressively sophisticated outputs. See [WEB_ENHANCED_GUIDE.md](WEB_ENHANCED_GUIDE.md) for details.
### Running SDG Network Visualizations (NEW!)
Generate progressive SDG (Sustainable Development Goals) network visualizations with automatic API discovery:
```bash
# Single SDG network visualization
/project:infinite-web specs/sdg_network_progressive.md sdg_viz 1
# Small batch (5 iterations, different APIs)
/project:infinite-web specs/sdg_network_progressive.md sdg_viz 5
# Medium batch with progressive techniques
/project:infinite-web specs/sdg_network_progressive.md sdg_viz 12 specs/sdg_network_url_strategy.json
# Infinite mode - continuous API discovery and visualization improvement
/project:infinite-web specs/sdg_network_progressive.md sdg_viz infinite specs/sdg_network_url_strategy.json
```
**Key Features:**
- Automatic discovery of open APIs (environmental, scientific, SDG data)
- Force-directed network graphs with D3.js
- Progressive enhancements: node colors, edge strength, interactivity
- Each iteration integrates new data sources and visualization techniques
- See [SDG_NETWORK_GUIDE.md](SDG_NETWORK_GUIDE.md) for complete guide

- Proper implementation of learned technique
- Original application (not copy-paste)
- Comments explaining the technique
- Visual proof that it works
## Ultra-Thinking Directive
Before each Three.js visualization, deeply consider:
**Web Learning Strategy:**
- What specific Three.js technique does this URL teach?
- How can I extract the most valuable knowledge from this source?
- What code patterns or concepts are most important?
- How does this build on previous iterations' learnings?
**Technical Implementation:**
- What's the most effective way to apply this technique?
- How can I ensure smooth 60fps performance?
- What Three.js APIs are most appropriate?
- How should shaders or materials be structured?
**Visual Design:**
- What makes this visualization aesthetically compelling?
- How does lighting enhance the scene?
- What camera angle best showcases the technique?
- How can animation improve the experience?
**Progressive Building:**
- How does this iteration advance beyond previous ones?
- What new complexity is introduced?
- Can I combine techniques from earlier iterations?
- What's the next logical step in the learning path?
**Quality Assurance:**
- Does the code clearly demonstrate the learned technique?
- Is the web source properly attributed?
- Would someone learn from viewing this example?
- Is the implementation unique and creative?
## Success Criteria
A successful Three.js iteration:
- **Runs Perfectly**: No errors, smooth 60fps animation
- **Demonstrates Learning**: Clear application of web-sourced technique
- **Looks Beautiful**: Visually engaging and well-crafted
- **Is Self-Contained**: Single HTML file works standalone
- **Documents Sources**: Clear attribution and learning explanation
- **Shows Progression**: Builds on previous iterations appropriately
- **Teaches Others**: Code quality that others can learn from
Generate Three.js visualizations that showcase the power and beauty of modern 3D web graphics while demonstrating genuine progressive learning from web resources.
