A pie chart displays 2022 U.S. auto sales by brand, with each slice sized by year-to-date sales. Percentages and sales values (in thousands) are shown in a legend. Built with D3 v5, the visualization loads CSV data via `d3.csv`, computes pie arc paths with `d3.pie`, and renders them as SVG paths using `d3.arc`. A sequential `d3.scaleOrdinal` color scheme distinguishes brands. The chart is centered in a 960×450 SVG canvas, with legends positioned to the right.
