This pie chart visualizes how vehicles in the CarPerformance dataset are distributed across three horsepower ranges: low (≤120 HP), medium (121–160 HP), and high (>160 HP). Each slice’s size reflects the count of vehicles in that category, with colored segments and a legend for identification. The visualization loads data from a CSV file using `d3.csv`, then applies `d3.pie` and `d3.arc` generators to create the slices. A `d3.scaleOrdinal` color scale maps the categories to distinct colors, while `arcGen.centroid` positions the labels within each slice.
