The visualization compares a node-link diagram with an adjacency matrix for the same network, rendered side-by-side. It uses D3.js v4 with a force-directed simulation (`d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`) for the node-link layout, while the matrix is drawn with SVG rectangles. Users can drag nodes and zoom, with interactions highlighting links and nodes. The data comes from the `infect-dublin.edges` file, and node colors indicate class groupings.
