This example compares two visualizations of the same network dataset: a force-directed node-link diagram on the left and an adjacency matrix on the right. The node-link diagram uses a physical simulation to position nodes, with link thickness and node color indicating degree and size. The adjacency matrix displays connections as filled cells in a grid. Both visualizations are built with D3 v3, using the `d3.layout.force` and `d3.behavior.zoom` APIs for the diagram, and a custom grid for the matrix. The matrix allows clicking to explore connections, while the node-link view supports zooming, dragging, and clicking. Data is loaded from a text file of edge pairs.
