Removes problematic Google Charts dependency and creates a cleaner,
more reliable performance trend visualization.
Changes:
- Remove all Google Charts JavaScript code (100+ lines)
- Replace chart with visual timeline showing each review chronologically
- Each timeline item displays:
* Date at top, reviewer name at bottom
* Colored circular badge with score number (green=5, blue=4, yellow=3, red<3)
* Horizontal progress bar showing score percentage with comments
- Add smooth animations: fade-in on load, scale on dot hover, slide on bar hover
- Color-coded by score for instant visual feedback
- Fully responsive with mobile layout
- No external dependencies - pure CSS solution
- Add empty state with graph icon if no performance data
The timeline provides better visual hierarchy and eliminates the blank
space issue caused by Google Charts loading failures.
