This example uses D3’s force simulation to render a dynamic network of nodes connected by curved links. It shows how layout physics—repulsion, attraction, and centering—evolves over time, with node positions updating continuously via `d3.forceSimulation` and `simulation.on("tick")`. The visualization reads node and link data from a JSON structure and draws them as SVG circles and paths, using `d3.forceLink` for edge constraints and `d3.forceManyBody` for charge interactions. The code also incorporates a zoom behavior for panning and scaling the graph.
