This pie chart displays 2022 U.S. auto sales by brand, with each slice’s size proportional to the brand’s year-to-date sales. A legend on the right hand side lists each brand with its corresponding sales value in thousands. Built with d3.js v5, the visualization uses the `pie` layout and `arc` generator to create the SVG paths, with a `scaleOrdinal` color scheme for slice fills. Data is loaded from a CSV file via `csv` and formatted using `format`.
