This chart shows 2022 US auto sales by brand as a pie chart with a color-coded legend displaying each brand's name and sales volume in thousands. The visualization loads data from a CSV file hosted on a GitHub gist, then uses the D3.js pie, arc, and scaleOrdinal APIs to generate the chart and legend within an SVG container. Each segment's fill color is mapped based on the brand's year-to-date sales value, and legend values are formatted using the d3.format API.
