This pie chart visualizes annual car sales for different companies in India, sourced from a CSV file hosted on GitHub. The visualization displays each company’s sales as a slice with a proportional angle, color-coded via an ordinal scale, and includes a legend and value labels. Built with D3.js v5 and rendered as SVG, the code uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to structure the chart, with data fetched using `d3.csv`.
