{"version":"1.0","type":"rich","title":"task9_question1","description":"This example presents a pie chart of total sales by product line, using data from a supermarket sales CSV file. The chart uses D3.js v7 to create an SVG-based visualization with color-coded slices, a legend, and percentage labels. It demonstrates loading external data via `d3.csv` and performing aggregation with `d3.sum` and `d3.pie` to compute segment values. The code also uses `d3.scaleOrdinal` with `d3.schemeCategory10` for coloring and interactive hover effects that modify slice opacity, all rendered in the browser through the SVG API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3999f7ab4c54e3e90f99c45e2f7617c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
