{"version":"1.0","type":"rich","title":"Activity 7.1","description":"This D3.js pie chart visualizes the distribution of car makes from a CSV file loaded from a GitHub repository. It uses `d3.pie` and `d3.arc` to generate the pie slices, with `d3.scaleOrdinal` and `d3.schemeCategory10` providing the categorical color scheme. The chart displays percentage labels on each segment and includes a legend generated with HTML. Data is aggregated using `d3.rollups` to count occurrences of each make, and the SVG output is rendered within a centered layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cba3eacde8f64ae8b8914396f0555155?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
