This fork of a D3.js social network graph visualizes connections between people as a force-directed network. Yellow circular nodes represent individuals, while labeled, arrowed links depict friendship relationships with varying weights. The visualization uses `d3.forceSimulation` with link, charge, collision, and center forces to position nodes dynamically. Users can drag nodes to explore the network, and hovering highlights a node with a green outline. Data is loaded from a local JSON file and rendered as SVG elements.
