This pie chart visualizes the share of total goals or points contributed by each sport—football, basketball, and cricket—using data from SportsData.csv. The chart aggregates player statistics via `d3.rollup` and `d3.sum`, then renders slices with `d3.pie` and `d3.arc`, using a Tableau10 color scale from `d3.scaleOrdinal`. Labels appear on each slice using `labelArc.centroid`, and a legend lists the sports. The visualization is built with D3 v7 and rendered as SVG, with dark-themed styling applied.
