This pie chart displays revenue distribution by category, with slices labeled directly and a legend to the right. Built with D3 v7, it loads CSV data from a GitHub gist, aggregates revenue using d3.rollup and d3.sum, and renders SVG paths via d3.pie and d3.arc. A d3.scaleOrdinal with the Tableau10 color scheme maps categories to colors, while text elements label each slice.
