This example displays literacy rates for Southern Indian states as a pie chart, with each state’s name labeled on its slice and a color-coded legend showing the percentage value. Using D3.js v5, the code loads CSV data from a GitHub gist, then applies `d3.pie` and `d3.arc` to generate SVG paths, with `d3.scaleOrdinal` assigning colors. State names are placed via `arcGenerator.centroid`, while the legend lists each state and its formatted literacy percentage.
