This pie chart visualizes annual car sales for different companies in India, with each slice labeled with its sales value in thousands and accompanied by a color-coded legend. The chart uses D3.js version 5's `pie` and `arc` generators to create the segments from CSV data loaded via `d3.csv`, with `scaleOrdinal` assigning distinct colors to each company and `format` handling numeric labels. The SVG is rendered at 960×500 pixels with a center translate of (250,250) for the pie.
