Social Network Graph
This social network graph visualizes friendship connections among eight named individuals, with nodes arranged through a force-directed layout and directed edges indicating relationship direction. Built with D3 v6, the visualization uses `d3.forceSimulation` with link, charge, and collision forces to position overlapping nodes, while each person appears as a red circle with an ID label and arrowed lines marking connections. Interaction includes dragging nodes via `d3.drag` and hover effects that highlight a node with a green stroke. Data comes from a local JSON file containing node groups and repeated link entries, rendered as SVG elements with markers for arrowheads.
