{"version":"1.0","type":"rich","title":"Task9_Q1","description":"This example shows a pie chart of supermarket sales totals aggregated by product line, with a legend listing each category. It loads CSV data from a GitHub Gist, uses `d3.nest()` and `d3.sum` to aggregate totals per product line, and renders the chart with `d3.pie()` and `d3.arc()`. The visualization uses `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG elements for the arcs and legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f13fd32e67b64a588a931cf7ca6f4f6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
