The chart is built with D3.js v7, loading CSV data from a GitHub gist, and uses `d3.pie` and `d3.arc` to generate the slices. A categorical color scale maps the four classes, while text labels and the legend are positioned using SVG transformations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3059266027734a45bd7d77fb2fdcdf7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
