A fork of a force-directed graph compares node-link and adjacency-matrix views of a network. Clicking a node in the graph, or a cell in the matrix, highlights the corresponding row and column or links. The graph uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter, while the matrix renders as SVG rectangles scaled by edge weight. Both views support zooming and dragging via d3.drag and d3.zoom, with node colors mapping to group values.
