This example presents an interactive visualization built with React and D3.js, showing a force-directed network layout. The graph uses `d3.forceSimulation` to arrange nodes with physics-based movement, while CSS and JavaScript handle the minimal page structure. A `d3.geoPath` layer renders geographic boundaries beneath the network, and the code employs Canvas’s `getImageData` for pixel-based analysis. The visualization reads data from an external source and updates the layout dynamically, demonstrating a hybrid approach combining spatial mapping with network graph rendering.
