{"version":"1.0","type":"rich","title":"Fork of Pie Chart","description":"This visualization displays 2022 US auto sales by brand as a donut-style pie chart, with each brand's proportional market share represented by a colored arc segment. The chart includes a custom legend showing each brand, its sales volume in thousands, and its percentage of total sales. The code loads CSV data from a GitHub Gist and renders the chart as an SVG using D3 v5's `pie`, `arc`, and `scaleOrdinal` functions for segment layout and color assignment. Legends are manually constructed with appended `rect` and `text` elements, with formatting applied via D3's `format` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c12e4e7e985847dd8c91cd4b02ec298f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
