This example demonstrates a real-time force-directed network visualization, displaying nodes and edges that dynamically adjust their positions based on simulated physical forces. The graph uses `d3.forceSimulation` to compute node movement and repulsion, while SVG elements render the resulting structure. The visualization includes interactive controls for adjusting simulation parameters, and the node positions update every frame via a custom animation loop. The code uses the React framework to manage state and re-render the D3-based scene, with the simulation data loading from a JSON file.
