{"version":"1.0","type":"rich","title":"6-piechart","description":"This example shows the distribution of billionaires across categories using a single pie chart. The chart is rendered as an SVG with colored slices, labels for larger segments, and a legend that displays each category's name and count. The code aggregates the CSV data with `d3.rollup`, generates the pie geometry with `d3.pie` and `d3.arc`, and assigns colors via `d3.scaleOrdinal` with a categorical scheme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e4b3d47a258473e8800c0ee6ef11487?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
