This social network graph visualizes friendship connections among ten people, with green circular nodes and blue directed edges carrying arrow markers. The visualization uses D3.js v6 with a force-directed simulation (`d3.forceSimulation`) that applies link, charge, collision, and centering forces to position nodes. Nodes are draggable and highlight on hover, while the data comes from a local JSON file containing node and link objects. The SVG rendering includes custom markers defined in the `defs` section, with text labels displayed inside each node.
