This pie chart shows the sales distribution of cars across six manufacturers, with Ferrari, Mercedes, Audi, Porsche, BMW, and Mclaren. The visualization highlights proportional market share using a color-coded legend that displays each manufacturer’s percentage of total sales. Built with D3.js v5, the chart uses `d3.pie` and `d3.arc` to generate the SVG paths, while `d3.scaleOrdinal` with `schemeCategory10` assigns colors. Data is hardcoded in the script, and the rendering uses SVG elements with a legend created manually via appended rectangles and text labels.
