It uses D3 v7 modules including `d3.rollup`, `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to create colored arcs with labeled slices. A legend is appended to the SVG, and the chart is generated inside a group transformed to the center of the canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1aa7ba69c62848b9a546587e02da1123?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
