{"version":"1.0","type":"rich","title":"Activity_7_Q1","description":"This visualization displays the distribution of car classes in a dataset using a donut-style pie chart. The chart renders four categories—unacc, acc, vgood, and good—with colored arcs and percentage labels, alongside a legend showing class names and counts. Built with D3 v7, it loads CSV data externally, uses `d3.pie` and `d3.arc` for slice geometry, and applies `d3.scaleOrdinal` for categorical colors. Labels are positioned via arc centroids, and the SVG output includes a title and styled legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99dadcc059124e939e1abc80226c4fbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
