A force-directed graph represents a student collaboration network, with six tomato-colored nodes for students and gray links for their connections. Built with d3.v7, it uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` forces to position nodes. The SVG rendering updates node and label positions on each simulation tick. Users can drag nodes, which adjusts the simulation's alpha target to pause or restart the layout.
