A force-directed network diagram visualizes relationships among eight tech companies, categorized as Software, Hardware, E-commerce, or Cloud/AI. Node color encodes category, while node size reflects connection count, and edge style encodes partnership, competition, or collaboration type. The visualization uses D3 v7's `forceSimulation` with `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide`, rendering nodes as SVG circles with labels and tooltips.
