This pie chart visualizes the percentage contribution of individual players to sports, sourced from a CSV file of players and their sports contributions. Built with D3.js v5, it generates an SVG pie chart where each slice is labeled with the student's name and colored using a categorical scale. A legend on the right maps colors to players, displaying their exact contribution percentages formatted with d3.format. The visualization uses d3.pie, d3.arc, and d3.scaleOrdinal to construct the chart and its interactive elements.
