{"version":"1.0","type":"rich","title":"Task9_Question1","description":"A pie chart visualizes the distribution of patient counts by race, with each slice labeled directly and accompanied by a color-coded legend. The chart loads CSV data from a GitHub gist and uses D3 v7 APIs including `d3.rollup` to aggregate counts, `d3.pie` for layout, `d3.arc` for slice geometry, and `scaleOrdinal` with `schemeCategory10` for colors. Labels are positioned using `arcGenerator.centroid`, and the SVG rendering is centered within a 400×400 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/813154baa185421f9fe189e5f596e6aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
