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.
