## WEEK 1: Charts & Visualizations

### Day 1 - November 23, 2025
**Status**: Sprint started! 🎉
**Phases completed**:
- [x] Phase 3.1: Chart Library Setup ✅

**Sprint Setup**:
- [x] Created Sprint 3 directory structure
- [x] Created comprehensive sprint plan
- [x] Created sprint log template
- [ ] Ready to begin Phase 3.1

**Current Phase**: Phase 3.1 - Chart Library Setup

**Next Steps**:
1. Decide between Chart.js and Plotly.NET
2. Install chosen library
3. Create JSInterop wrapper
4. Test with simple chart

**Notes**:
- Sprint 2 is complete with all 15 phases done ✅
- Data pipeline is working (repos, commits, PRs all syncing)
- Metrics calculation is working
- Ready to visualize the data!

**Time Spent Today**: ~10 minutes (setup)
- [x] Phase 3.1 completed!

**What I implemented**:
- Integrated Chart.js 4.4.0 via CDN
- Created JSInterop wrapper (`wwwroot/js/charts.js`)
- Implemented `LineChart.razor` component with proper lifecycle
- Added component-scoped CSS styling
- Added test chart to dashboard with dummy data
- Implemented `IAsyncDisposable` for proper cleanup

**What I learned**:
- **JavaScript Interop (JSInterop)**: How Blazor communicates with JavaScript libraries
- `IJSRuntime.InvokeVoidAsync()` for calling JS functions
- Passing complex objects from C# to JavaScript
- **Component Lifecycle**: `OnAfterRenderAsync(firstRender)` for chart initialization
- Why `firstRender` check is important (prevents re-initialization)
- **Async Disposal**: `IAsyncDisposable` pattern for cleanup
- Prevents memory leaks by destroying Chart.js instances
- **Canvas Elements**: How charts render using HTML5 canvas
- **Unique IDs**: Using `Guid.NewGuid()` for multiple chart instances

**Decision Made**:
- ✅ **Chart.js** chosen over Plotly.NET
- Reasoning: Lightweight, excellent performance, great documentation, industry standard

**Challenges Solved**:
- Function name mismatch: `createChart` vs `createLineChart`
- Fixed typo: "Balzor" → "Blazor"

**Testing**:
- ✅ Chart renders correctly on dashboard
- ✅ Chart is responsive (resizes with window)
- ✅ No console errors
- ✅ Proper disposal verified

**GitHub**:
- Issue: #110 [SPRINT 3] Phase 3.1: Chart Library Setup
- Branch: `sprint3/phase3.1-chart-setup-#110`
- Committed and pushed
- PR created and ready to merge

**Time Spent Today**: ~3 hours (setup + implementation + testing)
