This example shows a force-directed graph of military equipment programs, with nodes colored by military branch and links representing dependencies between programs. Hovering highlights connected nodes and labels, while dragging lets users rearrange the layout. The visualization uses `d3.forceSimulation` for both graph and label positioning, `d3.zoom` for panning and scaling, and `d3.drag` for node interaction. Data comes from a local JSON file, rendered with SVG elements including circles, lines, and text labels.
