{"version":"1.0","type":"rich","title":"Question 2: Pie Chart","description":"This example visualizes product revenue distribution as an interactive pie chart, with slices colored by product and sized by aggregated revenue from a CSV file loaded via `d3.csv()`. The SVG-based chart uses `d3.pie()` and `d3.arc()` to generate the slices, while hovering highlights a slice with a `transition` animation. A legend and title accompany the chart, and the background uses a CSS gradient. The chart sorts products by revenue and uses an ordinal color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35cd39f2661c43408a2e4facb356f12a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
