This network graph uses D3.js (v7) to visualize six named nodes and their connections as a force-directed layout. The example combines `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute positions, rendered as SVG circles, lines, and text labels. Nodes are draggable via the `d3.drag` API, allowing manual repositioning that influences the simulation. The graph is generated from a static dataset defined in the JavaScript code, with default styling applied via CSS.
