{"version":"1.0","type":"rich","title":"Actvity 7.1.1","description":"This pie chart depicts the distribution of car models by brand, aggregated from a CSV file of individual car records. The visualization uses D3 v5 to generate SVG arcs, with an interactive tooltip revealing each brand's model count and percentage on hover. A legend displaying brand names, color swatches, and formatted model counts accompanies the chart, and the code explicitly uses `d3.pie`, `d3.arc`, `scaleOrdinal`, and `schemeCategory10` for rendering and color assignment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9560028f60bd47ff8b7018fbddeb78db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
