{"version":"1.0","type":"rich","title":"Pie plot","description":"A pie chart shows the distribution of stroke cases across BMI categories—Normal, Overweight, and Obese—as percentages of the total. The dataset is loaded via `d3.csv` from a GitHub gist, with BMI values filtered to stroke patients and grouped into the three categories. Using D3 v6, the chart is rendered as SVG paths generated by `d3.pie` and `d3.arc`, with a `d3.scaleOrdinal` color scheme. A legend, positioned via `d3.selectAll`, displays each category’s name and its computed percentage.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d1f8a2431284958a77d0815816efa5e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
