A pie chart displays annual car sales for different companies in India, with each slice labeled with its sales value in thousands and a corresponding color-coded legend listing company names and values. The visualization loads CSV data from a GitHub gist using `d3.csv` and renders the chart as SVG. It employs `d3.pie` and `d3.arc` to generate the pie segments, `d3.scaleOrdinal` for color mapping, and custom formatting with `d3.format` to abbreviate sales numbers.
