{"version":"1.0","type":"rich","title":"Pie Chart","description":"A pie chart built with D3 v7 displays the distribution of car types from a CSV file hosted on a GitHub Gist. The visualization aggregates raw records into categorical counts by type—Sedan, SUV, Truck, and Coupe—and shows each segment's percentage share using `d3.scaleOrdinal` with the `d3.schemeSet2` palette. D3's `arc` generator positions slices, while leader lines and external labels annotate each wedge. An interactive legend, populated via the `d3.select` API, highlights corresponding slices on hover, and a tooltip provides additional detail. The chart uses SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c5f6da1f6294339a60e741b39c35da1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
