This pie chart displays 2022 US auto sales by brand, showing each brand’s share as a percentage and raw sales in thousands. The visualization uses a static SVG rendered with D3 v5, where slices are generated via `d3.pie` and `d3.arc`, with colors assigned using `d3.scaleOrdinal`. Legends are manually appended, listing each brand, its percentage, and sales volume. Data is loaded asynchronously from a CSV file hosted in a GitHub gist using `d3.csv`, with numeric sales values parsed before rendering.
