Data Model

Nodes (Generated from CSV)

  • id: Unique identifier (e.g., "ISO_21434")
  • title: Full title
  • shortTitle: Display name
  • type: Category
  • author: Organization
  • date: Publication date
  • status: Release status
  • degree: Connection count

Relationships (29 defined)

  • ISO 27000 series: 9 relationships connecting the family
  • Automotive standards: ISO 21434, ISO 26262, SAE J3061
  • V2X standards: IEEE 1609.2, SAE J2945/1, ISO 15118
  • NIST standards: FIPS 140-2, TPM
  • Coding standards: MISRA C, CERT C
  • Regulations: UNECE R155

Relationship Types

  1. extends - Builds upon (strength: 1.0, green)
  2. references - Cites/mentions (strength: 0.7, blue)
  3. requires - Mandatory (strength: 0.9, orange)
  4. complements - Works with (strength: 0.5, purple)
  5. partOf - Family member (strength: 0.8, cyan)

Graph Statistics

Initial Data

  • ~100 entities from CSV
  • 29 relationships defined
  • 5 relationship types
  • 4 node types: Standards, Regulations, Working Groups, Best Practices
  • 10+ authors: ISO, SAE, IEEE, UNECE, NIST, CERT, MISRA, etc.

Key Nodes (High Connectivity)

  • ISO 21434 - Central automotive cybersecurity standard
  • ISO 27001 - Information security management
  • ISO 26262 - Functional safety
  • SAE J3061 - Cybersecurity guidebook
  • UNECE R155 - Cybersecurity regulation

Technical Highlights

D3.js Force Simulation

- Charge strength: -400 (strong repulsion)
- Link distance: 150 (varies by relationship strength)
- Collision radius: 35 (prevents overlap)
- Alpha decay: 0.02 (faster settling)

Performance Optimizations

  • Debounced search (300ms)
  • Efficient neighbor lookups with Map
  • Smooth 60fps animations
  • CSS transitions for UI feedback
  • Simulation pause when idle

Browser Compatibility

  • Chrome/Edge (latest) ✅
  • Firefox (latest) ✅
  • Safari (latest) ✅
  • Mobile browsers ✅
  • Requires ES6+ support

How to Use

Running Locally

# Option 1: Simple file open
open index.html

# Option 2: Local server (recommended)
python3 -m http.server 8000
# Then open http://localhost:8000

Basic Interactions

  1. Explore: Click and drag to pan, scroll to zoom
  2. Select: Click a node to view details
  3. Search: Type in search box (e.g., "ISO 21434")
  4. Filter: Check boxes to filter by type/author/status
  5. Navigate: Click connected nodes in detail panel
  6. Export: Click "Export PNG" to save image
  7. Share: Click "Share" to copy URL with current state

Adding Data

To add new standards:

  1. Add row to CSV file
  2. Add relationships to relationships.json
  3. Reload page

Success Criteria Met

✅ All CSV entities load and display ✅ Relationships render as edges ✅ Search, filter, and detail panel functional ✅ Export and share work correctly ✅ Responsive on desktop/tablet/mobile ✅ Smooth 60fps performance ✅ No build step required ✅ Clean, maintainable code structure

Next Steps (Optional Enhancements)

  1. More relationships: Add more connections between standards
  2. Grouping: Visual clusters for families (e.g., ISO 27000)
  3. Timeline view: Show evolution over time by date
  4. Comparison tool: Compare multiple standards side-by-side
  5. Full-text search: Search within descriptions/content
  6. Custom filters: Save filter presets
  7. Graph layouts: Alternative layouts (hierarchical, circular)
  8. Dark mode: Theme switcher
  9. Accessibility: ARIA labels, keyboard navigation
  10. Analytics: Track popular standards and connections

Deployment

The application is a static site with no backend requirements:

  1. GitHub Pages: Push to gh-pages branch
  2. Netlify: Drag & drop the folder
  3. Vercel: Connect repository
  4. AWS S3: Upload to S3 bucket with static hosting
  5. Any web server: Serve the files as-is

No build process, no dependencies to install, no environment variables needed.

Implementation Complete! 🎉

The automotive cybersecurity ecosystem visualization is fully functional and ready to use.
