{"version":"1.0","type":"rich","title":"Activity7:Questions:1","description":"This visualization uses a D3.js pie chart to show the distribution of car fuel types, with slices representing the proportion of cars using each fuel type. The data is loaded from a CSV file via `d3.csvParse` and grouped with `d3.rollup` to count cars by fuel category. The chart is rendered as SVG using `d3.pie()`, `d3.arc()`, and a color scale from `d3.schemeCategory10`, with labels placed at each arc’s centroid.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b0ef1d0f2804e8bb6d29bbf04c8194d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
