This interactive SVG social network graph visualizes 10 people and their friend relationships, with each node drawn as a large orange circle labeled with a name and connected by directed, arrow-tipped lines. The code uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, `d3.forceCollide`, and `d3.forceCenter` to position nodes, while link values indicate relationship strength. Nodes are rendered as SVG circles and are draggable via `d3.drag`, with hover effects that thicken the node border.
