This example shows a small friendship network of six named people (Alice, Bob, Cathy, Dan, Ella, and Frank) connected by six links, rendered as an SVG. It uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to position nodes, which are drawn as green circles with text labels. Links appear as gray lines updated on each simulation tick. Nodes are draggable via d3.drag, which temporarily fixes their positions during interaction.
