This example visualizes a force-directed graph alongside an adjacency matrix, using the infect-dublin dataset. Users can click nodes in the graph or cells in the matrix to highlight connected links and corresponding rows or columns. The graph is rendered with SVG circles and lines, positioned via `d3.forceSimulation`, `forceLink`, `forceManyBody`, and `forceCenter`. The matrix uses SVG rectangles with fill opacity representing link weights, and both views support zooming through `d3.zoom` and interactive dragging.
