This example shows a small force-directed network of six nodes (A–F) connected by weighted links, with node color encoding gender and labels revealing name and profession on hover. It includes an adjacency matrix table above the visualization. The code uses D3 v7's `d3.forceSimulation` with link, charge, and center forces, rendering nodes and links as SVG elements. Nodes are draggable via `d3.drag`, and the data comes from a static JSON file.
