{"version":"1.0","type":"rich","title":"PieChart Fork","description":"This pie chart visualizes income distribution (above or below $50K) using data from the UCI Adult dataset, loaded via D3’s `d3.csv` from a remote GitHub repository. It computes category counts with `d3.nest()` and `rollup`, then renders SVG arcs using `d3.pie()` and `d3.arc()`. A legend maps label colors via `d3.scaleOrdinal`, while the chart groups slices in a centered `<g>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d10baa466634b8daa3fb12db8aca7f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
