This visualization displays a network graph of nodes and links derived from a tab-separated dataset, rendered as an interactive SVG. The code builds an adjacency matrix and visualizes it as a grid of colored rectangles, while a separate force-directed layout using `d3.forceSimulation` positions the nodes and links. Nodes are colored based on their degree, and both the matrix cells and graph nodes respond to click events, though the click handlers only log to the console. The visualization also supports zooming and panning via a zoom behavior.
