This pie chart visualizes the top ten restaurants by daily biryani sales, using color-coded slices to represent each hotel’s total units sold per day. The visualization loads CSV data from a GitHub gist, processes it with `d3.pie()` and `d3.arc()` to generate the chart, and applies `d3.scaleOrdinal` with `schemeCategory10` for coloring. Hovering over a slice logs its sales value to the console. Legends display restaurant names and formatted sales values, all rendered as SVG within a React-based D3 v5 setup.
