It uses d3.csv for data loading, d3.pie and d3.arc for chart generation, d3.scaleOrdinal for color mapping, and d3.format for value labeling, with the chart centered in a fixed-width SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/313561689f664aa4a97a67242a4757c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
