This pie chart shows the top billionaires in the world and their net worth in billions of U.S. dollars, using a dataset from a GitHub-hosted CSV file. Each slice is labeled with its dollar value, and a legend lists billionaire names alongside their corresponding worth. The chart is built with D3 v6 and rendered as an SVG, using the `d3.pie` and `d3.arc` generators to compute and draw the sections. Colors are assigned via `d3.scaleOrdinal`, and the visualization includes formatted numeric labels and a custom legend.
