{"version":"1.0","type":"rich","title":"Question 1","description":"This pie chart displays vehicle registration counts by type, using color-coded sections with value labels and a legend that pairs each category with its numeric count. The chart is rendered as an SVG using D3 v5, loading data from a CSV file via the `d3.csv` function. The visualization employs D3's `pie`, `arc`, and `scaleOrdinal` APIs to generate the sectors and colors, while the legend and labels are built using D3's `select` and `append` methods. The styling is defined in a separate CSS file, and the code demonstrates the use of ES6 modules for data fetching and rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ac0adf698b74885821ea2fdfac5112e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
