feat(#72): implement interactive graph visualization component
- Create KnowledgeGraphViewer component with @xyflow/react - Implement three layout types: force-directed, hierarchical (ELK), circular - Add node sizing based on connection count (40px-120px range) - Apply PDA-friendly status colors (green=published, blue=draft, gray=archived) - Highlight orphan nodes with distinct color - Add interactive features: zoom, pan, click-to-navigate - Implement filters: status, tags, show/hide orphans - Add statistics display and legend panel - Create comprehensive test suite (16 tests, all passing) - Add fetchKnowledgeGraph API function - Create /knowledge/graph page - Performance tested with 500+ nodes - All quality gates passed (tests, typecheck, lint) Refs #72 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# Issue #72: Graph Visualization Component
|
||||
|
||||
## Objective
|
||||
|
||||
Create interactive knowledge graph visualization component in Next.js web UI using the graph API from issue #71.
|
||||
|
||||
## Approach
|
||||
|
||||
1. Research and select graph visualization library
|
||||
2. Follow TDD: Write tests before implementation
|
||||
3. Create graph visualization component with:
|
||||
- Force-directed layout
|
||||
- Node sizing based on connections
|
||||
- PDA-friendly status colors
|
||||
- Click handlers for navigation
|
||||
- Zoom/pan controls
|
||||
- Layout toggle options
|
||||
4. Performance test with 500+ nodes
|
||||
5. Integrate with graph API
|
||||
|
||||
## Library Selection
|
||||
|
||||
Evaluating options:
|
||||
|
||||
- **react-force-graph**: WebGL-based, high performance, good for 500+ nodes
|
||||
- **vis-network**: Canvas-based, feature-rich
|
||||
- **d3-force**: Low-level, full control but more complex
|
||||
|
||||
**Decision: react-force-graph-2d**
|
||||
|
||||
- Best performance for 500+ nodes (WebGL rendering)
|
||||
- Simple API
|
||||
- Built-in zoom/pan
|
||||
- Easy to customize node appearance
|
||||
- Active maintenance
|
||||
|
||||
## Progress
|
||||
|
||||
- [x] Create scratchpad
|
||||
- [x] Set up component structure
|
||||
- [x] Write tests (TDD) - 16 tests, all passing
|
||||
- [x] Implement basic graph rendering
|
||||
- [x] Add node sizing logic (based on connection count)
|
||||
- [x] Add status-based coloring (PDA-friendly colors)
|
||||
- [x] Implement click handlers (navigation to entry)
|
||||
- [x] Add layout controls (force, hierarchical, circular)
|
||||
- [x] Performance testing (supports 500+ nodes)
|
||||
- [x] Create display page at /knowledge/graph
|
||||
- [x] Add filters (status, tags, orphans)
|
||||
- [x] Type checking passes
|
||||
- [x] Linting passes
|
||||
- [ ] Code review
|
||||
- [ ] QA checks
|
||||
- [ ] Commit and close issue
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
1. Unit tests for graph component
|
||||
2. Test node rendering
|
||||
3. Test interaction handlers
|
||||
4. Test layout switching
|
||||
5. Performance test with large datasets
|
||||
|
||||
## PDA-Friendly Colors
|
||||
|
||||
From CLAUDE.md:
|
||||
|
||||
- 🟢 Active: green-500
|
||||
- 🔵 Scheduled: blue-500
|
||||
- ⏸️ Paused: yellow-500
|
||||
- 💤 Dormant: gray-400
|
||||
- ⚪ Archived: gray-300
|
||||
|
||||
## Implementation Summary
|
||||
|
||||
### Components Created
|
||||
|
||||
1. **KnowledgeGraphViewer.tsx** - Main graph visualization component
|
||||
- Force-directed, hierarchical, and circular layout options
|
||||
- PDA-friendly status colors (green=published, blue=draft, gray=archived)
|
||||
- Node sizing based on connection count
|
||||
- Interactive zoom/pan controls
|
||||
- Click to navigate to entry
|
||||
- Filters: status, tags, orphan visibility
|
||||
- Legend panel showing color meanings
|
||||
|
||||
2. **KnowledgeGraphViewer.test.tsx** - Comprehensive test suite
|
||||
- 16 tests covering all features
|
||||
- 100% test pass rate
|
||||
- Performance test with 500+ nodes
|
||||
|
||||
3. **page.tsx** - Display page at /knowledge/graph
|
||||
|
||||
### API Integration
|
||||
|
||||
- Added fetchKnowledgeGraph() to knowledge.ts API client
|
||||
- Fetches from /api/knowledge/graph endpoint (implemented in issue #71)
|
||||
- Supports filtering by tags, status, and limit
|
||||
|
||||
### Libraries Used
|
||||
|
||||
- @xyflow/react - Graph rendering and layout
|
||||
- elkjs - Hierarchical layout algorithm
|
||||
- Already in package.json, no new dependencies needed
|
||||
|
||||
### Features Implemented
|
||||
|
||||
- ✅ Force-directed layout (default)
|
||||
- ✅ Hierarchical layout (ELK algorithm)
|
||||
- ✅ Circular layout
|
||||
- ✅ Node sizing based on connections (40px - 120px)
|
||||
- ✅ PDA-friendly colors by status
|
||||
- ✅ Orphan node detection and highlighting
|
||||
- ✅ Click to navigate to entry
|
||||
- ✅ Zoom and pan controls (ReactFlow built-in)
|
||||
- ✅ MiniMap for navigation
|
||||
- ✅ Filters: status, tags, show/hide orphans
|
||||
- ✅ Statistics display (total nodes, edges, orphans)
|
||||
- ✅ Legend panel
|
||||
- ✅ Performance tested with 500+ nodes
|
||||
|
||||
### Notes
|
||||
|
||||
- Using @xyflow/react instead of react-force-graph (already in dependencies)
|
||||
- Memoization implemented for filtered nodes/edges
|
||||
- Layout calculations are async to prevent UI blocking
|
||||
- All quality gates passed (tests, typecheck, lint)
