This network graph visualizes the friendships among eight individuals, showing the connections and relationships between them through a force-directed layout. The visualization uses D3 version 6 with the `d3.forceSimulation` API to manage the physics of node placement, incorporating forces for linking, collision detection, and centering. Nodes are rendered as circles with labels, while links are drawn as lines with arrow markers. The graph supports interactive dragging, and hovering highlights individual nodes through CSS class changes. Data is loaded from a JSON file containing link and node definitions.
