{"version":"1.0","type":"rich","title":"Question1-1 Anil","description":"This example shows a pie chart of car horsepower by make, with a color-coded legend for each manufacturer. Built with D3 v6, it loads CSV data from GitHub, parses numeric values, and uses `d3.pie` and `d3.arc` to generate the SVG slices. A `d3.scaleOrdinal` with `schemeCategory10` maps makes to colors, while `d3.csv` handles asynchronous data fetching. The chart includes a custom legend built from `color.domain()`, rendered as SVG rectangles and text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4165228c3a9452ab3dda4c6cb109325?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
