{"version":"1.0","type":"rich","title":"Activity 7.1","description":"A pie chart displays car production totals for countries in 2019, with a legend listing each country and its corresponding value in thousands. The visualization uses D3 v5 to load CSV data via the `csv` function from a GitHub gist, then processes it with `pie` and `arc` to generate the chart segments. `scaleOrdinal` assigns a categorical color palette, while `format` converts large numbers into a compact tick label format. The SVG output includes clickable paths and a separate legend group with circles and text elements positioned via `attr` transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5784dd882ea640b1acd44711a0aece96?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
