This example demonstrates a minimal interactive visualization built with React, combining a force-directed graph layout with geographic map projections. The code uses d3.forceSimulation to position nodes and d3.geoPath to render world map outlines, with data drawn from a static GeoJSON source. Users can explore the network by dragging nodes, while the map serves as a contextual backdrop. The implementation relies on React’s state management to update the visualization in response to interactions, showcasing a hybrid approach that integrates D3’s rendering capabilities within a React component lifecycle.
