This fork of a React starter demonstrates a real-time, interactive particle system rendered on an HTML canvas. It uses `d3.forceSimulation` to manage particle physics, with forces like charge and collision driving movement across the viewport. The `useRef` and `useEffect` React hooks manage the animation loop, continuously updating the canvas via `requestAnimationFrame`. The display shows a dense cluster of small circles that slowly dissipates and re-forms based on the configured force parameters, providing a live example of force-directed layout in a React component.
