The D3.js code uses `d3.scaleOrdinal` for categorical coloring, `d3.pie` for arc generation, and `d3.arc` for path construction, rendering to an SVG canvas. Labels appear at arc centroids, while a legend below maps colors to categories. The data is hardcoded in the script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/990ca6ba1b7f4bf690107223674b5d7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
