{"version":"1.0","type":"rich","title":"Q2","description":"This pie chart displays the share of total sales per year from a `company_performance.csv` file. The chart renders as an SVG and uses coordinates loaded from the file, which are parsed with `d3.timeParse` and grouped by year with `d3.rollup`. Slice paths are generated via `d3.pie` and `d3.arc`, while colors come from `d3.scaleOrdinal` with the `d3.schemeTableau10` palette. Labels are positioned using the arc centroid, and a legend lists each year. The document references the D3 library (v7.8.5) via a CDN and an external data source hosted on GitHub Gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4f22aa01c374c34bdb4e857662966bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
