This pie chart displays the net worth of the richest people, using a color-coded slice for each individual and a corresponding legend. The chart is generated with D3.js (v5), using the `d3.pie` and `d3.arc` functions to create the SVG segments, with data loaded from a CSV file via `d3.csv`. Custom colors and labels are applied through `d3.scaleOrdinal` and `d3.format` for axis tick values.
