This pie chart displays the sales rankings of 50 restaurant brands from the "Future50" dataset for 2020. Using D3 v5, the visualization generates SVG arcs with `d3.pie` and `d3.arc`, applying a categorical color scale for each segment. Value labels are positioned via `arc.centroid`, while a legend on the right lists restaurant names and their corresponding sales figures. Data is loaded asynchronously from a raw GitHub CSV file and processed with the `d3.csv` function.
