This example demonstrates a force-directed graph layout of 100 unlabeled nodes connected by 300 random links. The visualization shows how the network stabilizes over time as the D3 force simulation distributes nodes across a 400×400 SVG canvas. Using d3.forceSimulation, it applies d3.forceCenter to center the layout, d3.forceManyBody with weak negative charge to repel nodes, and d3.forceLink with a fixed distance to maintain edge lengths. Circles and lines are rendered as SVG elements, with positions updated on each tick event.
