{"version":"1.0","type":"rich","title":"Question 1","description":"This example visualizes vehicle registration counts by type as a pie chart. The code loads CSV data from a GitHub repository using `d3.csv` and maps the `Count` values to arc segments generated with `d3.arc` and `d3.pie`. Each slice is labeled with its value (formatted using `d3.format`), and a legend lists the vehicle types alongside their counts. The chart is rendered as an SVG with `d3.select`, with ordinal color scaling via `d3.scaleOrdinal` for the four categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/088d476f8b9143b88c84b8d62ba06e93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
