This interactive network visualization shows collaborations among eight researchers, with nodes colored by department (CS, Math, Physics, Design) and labeled with names. Built with D3.js v7, it uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to position nodes, while `d3.drag()` enables node dragging. Hovering reveals a tooltip with the person's department. The demo uses a small hardcoded dataset and renders to SVG.
