A donut chart displays wheat crop production across ten districts in Andhra Pradesh, with each slice sized by production value. The visualization uses D3 v4’s `d3.arc`, `d3.pie`, and `d3.scaleOrdinal` with the `schemeCategory10` color palette, rendered as SVG. Hover interactions adjust slice opacity and show a tooltip with district name and value, while a legend is built separately. Data originates from a CSV loaded via D3’s `csv` method within a React component using hooks.
