This network graph visualizes a small social network of named individuals and their friendship connections, loaded from a `graph.json` file. It shows nodes as large light green circles with names, connected by blue directed lines, where link thickness indicates relationship value. Using the D3 v6 library, the layout is computed with `d3.forceSimulation`, combining forces for link distance, many-body repulsion, and collision avoidance. The SVG rendering includes interactive dragging, with node highlighting on hover.
