This visualization presents a pie chart of top car company sales by price, with each slice labeled with its value and accompanied by a legend listing the corresponding model names. The chart uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the segments and map categorical colors, while the legend is built manually with SVG `rect` and `text` elements. Data is loaded from a GitHub Gist via `d3.csv` in a React-based setup, with the SVG rendered directly in the browser.
