This network graph shows the relationship between Maharashtra and its districts, with a large red central node representing the state connected to smaller blue nodes for each district. The code uses D3 v7’s `d3.forceSimulation` with `forceLink` and `forceManyBody` to position nodes, and SVG circles, lines, and text labels for rendering. It fetches crop data from a CSV via `d3.csvParse` and supports dragging nodes through D3’s drag handler.
