This force-directed node-link diagram visualizes the high-tech firm network from a CSV dataset, showing connections weighted by link strength. It uses D3 v7’s `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position nodes, while SVG lines and circles render the graph. Interactive tooltips appear on hover via D3 event handlers, and the animation updates positions on each tick event.
