# Description
Implement Pie Chart visualization support in dashboard components.
This PR adds pie chart visualization capability to the dashboard,
allowing users to:
- Render pie charts in the chat_dashboard mode
- Preview pie charts in the chat_dashboard editor mode
## Implementation Details
- Added new file: `web/components/chart/pie-chart.tsx` that implements
pie chart rendering logic using G2
- Modified `web/components/chart/index.tsx` to integrate the pie chart
component into the dashboard chart rendering flow
- Added animation effects, hover interactions, and improved legend
display
- Fixed interaction bugs to ensure smooth visualization
# How Has This Been Tested?
Testing procedure included:
1. Creating datasets with category-based data suitable for pie charts
2. Verifying pie chart visualization in chat_dashboard mode
3. Confirming preview functionality works correctly in the editor mode
4. Testing interactions: hover effects, animations, and legend display
All tests confirm the feature works as expected with proper
visualization of categorical data proportions.
