This social network graph visualizes eight people with links representing friendships, where link thickness indicates relationship strength and all nodes share a uniform yellow fill. The visualization uses a force-directed layout powered by `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCollide` to position nodes dynamically. Rendering occurs via SVG with draggable circle nodes, arrowhead markers on links, and hover styling that highlights the focused node in red. The data is loaded asynchronously from a JSON file containing explicit node and link definitions.
