This pie chart visualizes annual car sales by company in India, displaying each company's sales as a proportionally sized slice with labels in thousands and a color-coded legend. The chart uses D3 v5 APIs including `pie()`, `arc()`, and `scaleOrdinal()` to generate SVG paths, with data loaded from a CSV file. The visualization also incorporates `format()` for axis tick formatting and renders text labels positioned via `arcGenerator.centroid()`.
