This example presents two coordinated views of the same graph data: a force-directed node-link diagram rendered with d3.forceSimulation, and an adjacency matrix using reorder.js for layout. Clicking a node in the network highlights the corresponding row and column in the matrix, while clicking a matrix cell highlights its associated link. The matrix uses SVG rectangles with fill-opacity representing connection strength, and both views support zooming and dragging. The code imports d3 v6, d3-force, and reorder.js libraries.
