This visualization uses D3.js to simulate a force-directed network layout, drawing nodes as circles connected by curved links. The code employs `d3.forceSimulation` to compute positions and velocities, with link distances tuned by the `distance` accessor and repulsive forces via `forceCollide`. It renders onto an HTML canvas using the Canvas API, and the animation loop runs continuously via `requestAnimationFrame`. The data is hardcoded in a variable named `data`, containing node and link arrays, but no external dataset is loaded; the example focuses on demonstrating a custom force layout with adjustable parameters.
