{"version":"1.0","type":"rich","title":"Activity7.1_Q1","description":"This pie chart displays the average horsepower distribution across the top 10 car makers, with all remaining manufacturers aggregated into an \"others\" category. The visualization uses D3 v7's `d3.pie` and `d3.arc` generators to compute slice geometry, with `d3.scaleOrdinal` and `d3.schemeTableau10` providing color encoding. Data loads from a remote CSV file containing smartphone specifications, which the code aggregates and normalizes to percentages. Each slice includes percentage labels positioned via `arc.centroid`, while an HTML legend to the right maps colors to maker names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1988df3bdcca4f73a6b8d96b4a5a5127?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
