This example demonstrates a force-directed graph layout using React and D3.js. It renders a network of nodes and edges, where the positions of the nodes are computed by a physics simulation that iteratively resolves repulsive and attractive forces, creating a stable, readable cluster layout. The visualization uses a custom `d3.forceSimulation` implementation to manage the graph’s dynamics, while the rendering is handled through SVG paths and circles, driven by React’s state updates. The data structure and simulation parameters are defined directly in the code.
