This pie chart visualizes the top car sales in 2022, with each slice sized proportionally to the number of units sold and a legend displaying car names and sales counts. The chart renders using D3 v5’s `pie` and `arc` generators to compute segment geometry, with colors assigned via `scaleOrdinal` and `d3.schemeCategory10`. Data is loaded asynchronously from `carsales.json` using `d3.json`, and the SVG is built by appending `path` and `rect` elements. The presentation uses an SVG container with a legend offset to the side, and sales values are formatted with `d3.format`.
