{"version":"1.0","type":"rich","title":"My Task 9","description":"This example presents a pie chart visualizing car purchase percentages by brand, with a legend and axis labels. It loads a CSV dataset from a GitHub gist, and uses D3 v7 APIs including `d3.csv`, `d3.pie`, `d3.arc`, `d3.scaleOrdinal`, and `d3.schemeCategory10` to compute and render the arcs. The SVG chart is created in a container with a separate legend, and each slice includes a tooltip title showing the brand and percentage. The data is drawn directly from the remote CSV file, while the layout is fixed with explicit width and height margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec20d182665447bdb51e98dbb82faa6c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
