{"version":"1.0","type":"rich","title":"Activity_7.1_Question_1","description":"This pie chart displays vehicle types and their registration counts, with proportional slices labeled in thousands and a corresponding color-coded legend. It loads CSV data from a GitHub gist, calculates the pie layout using `d3.pie`, and renders SVG paths with `d3.arc`. The visualization uses `d3.scaleOrdinal` for slice colors, formats values with `d3.format`, and appends legend rectangles and text labels. The chart is centered in an SVG and includes a title, with values shown numerically inside each segment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc4e2a7ee4f64e65985fa4611c1fd945?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
