This pie chart displays the literacy rates of Southern Indian states, with each slice representing a state and its corresponding percentage. The visualization uses D3.js (v5) to render the chart as SVG, employing the `pie` and `arc` functions to generate the segments, `scaleOrdinal` for color mapping, and `arcGenerator.centroid` to position state labels. A legend with colored swatches and percentage values accompanies the chart. Data is loaded from a remote CSV file using D3's `csv` method, and formatting of the tick labels is handled with `format`.
