It aggregates data from a CSV file spanning US yearly data from 2009 to 2023. The visualization uses D3 v6 to generate pie slices with percentage labels, a color-coded legend, and a title. The code leverages D3's `pie`, `arc`, `scaleOrdinal`, and `csv` functions, rendering the chart as SVG with bright colors like green, blue, and black.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd90cbe2db694248a2436ba074c76f7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
