This example shows a social network graph with nine nodes representing names like Aero, MK, and Hollister, connected by curved links. Node size and color vary based on the number of connections, using the `d3.interpolateBlues` scale. The visualization uses `d3.forceSimulation` with link, charge, and centering forces to position the nodes, and renders everything as SVG elements. Links are drawn as curved paths, with green solid strokes for active connections and black dashed strokes for weaker ones. Users can drag nodes to reposition them, which the force simulation responds to in real time.
