This example visualizes a small network of ten unlabeled nodes connected by ten links as a force-directed graph. The simulation uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position the nodes, while user interaction is supported through `d3.drag` to move nodes. The code renders the graph in SVG, drawing links as lines and nodes as steelblue circles that update their positions on each simulation tick.
