## 🎯 Decision Framework

### When to Use ReactFlow

✅ Node count < 10,000
✅ Interactive editing required
✅ Rich UI needed (forms, drag-drop)
✅ Fast development timeline
✅ Team unfamiliar with WebGL

### When to Use Sigma.js

✅ Node count > 10,000
✅ Read-only exploration
✅ Performance critical
✅ Network analysis (clustering)
✅ Simple node styling acceptable

### When to Use Hybrid

✅ Variable graph sizes
✅ Different use cases (edit + explore)
✅ Future-proofing needed
✅ Can invest 5 weeks
✅ Want best of both

## 🎯 Recommendations Summary

### Primary Recommendation: Hybrid Approach

**Rationale:**
1. ✅ Best performance for large graphs (>10k nodes)
2. ✅ Keeps ReactFlow for interactive editing
3. ✅ Low risk with fallback mechanism
4. ✅ Future-proof scaling to 100k+ nodes
5. ✅ Reasonable implementation timeline (5 weeks)

**Implementation:**
- Week 1-2: ReactFlow optimizations
- Week 3-4: Sigma.js integration
- Week 5-6: Adaptive view implementation
- Week 7: Testing and launch

**Expected Results:**
- 60fps @ 10k nodes (both renderers)
- 30fps+ @ 50k nodes (sigma.js)
- <3s initial load
- Zero crashes on large graphs

---

### Alternative: ReactFlow Optimizations Only

**When to Choose:**
- Limited timeline (2 weeks)
- Risk-averse stakeholders
- All graphs currently <10k nodes
- No immediate need for 100k+ scaling

**Expected Results:**
- 30-50% FPS improvement
- Better memory management
- Still limited by SVG rendering
