The chart uses D3.js v5 APIs including `d3.pie` and `d3.arc` to generate the SVG paths, and `d3.scaleOrdinal` for slice coloring. Data is loaded asynchronously via `d3.csv` from a GitHub repository, with values formatted using `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b6a6990b93349caa91fa8980c8b217d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
