This example pairs an interactive force-directed node-link diagram with an adjacency matrix view of the same network data. Dragging nodes in the force simulation or clicking matrix cells highlights corresponding rows, columns, and links in both views. The code uses `d3.forceSimulation` with `forceLink` and `forceManyBody`, and renders as SVG with zoom support. The matrix cells encode link weights through fill opacity, while the node-link view reads edge data from the `infect-dublin.edges` dataset.
