{"version":"1.0","type":"rich","title":"Activity7_q1","description":"This example shows the distribution of car classification categories (unacc, acc, good, vgood) as a pie chart with a legend. It uses D3.js to load CSV data, compute category counts, and render the chart as an SVG via `d3.pie()`, `d3.arc()`, and `d3.scaleOrdinal()` for color mapping. Percentage labels are placed on slices using a separate arc for label positioning, and the legend lists each category with its count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81042ba898a0484bad77499f1847d3ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
