This example displays a small network of three circles labeled Alice, Isaac, and Andrew, connected by two links. The visualization uses d3.forceSimulation with d3.forceManyBody for repulsion, d3.forceLink to maintain edge distances, and d3.forceCenter to keep the graph centered. The rendering targets an SVG container, with each node represented as a 50-pixel-radius circle. The simulation logs a "tick" message on each update, while the initial circle elements are appended programmatically via the selection API.
