This pie chart visualizes the number of wins (labeled as goals) for top tennis players, using a CSV dataset fetched from a GitHub gist. The chart encodes each player’s total as a colored slice, with labels showing the value in thousands and a legend listing player names and their corresponding totals. Built with D3 v5 and rendered as SVG, the code uses `d3.pie` to compute arc angles, `d3.arc` for path generation, `d3.scaleOrdinal` for color assignment, and D3's `csv` for data loading.
