This interactive network diagram maps data flows between subscriber and network system components, with nodes grouped by category and colored by system type. The graph uses a force-directed layout via `d3.forceSimulation`, combining `forceY`, `forceX`, and `forceCollide` to organize nodes into vertical bands. SVG lines with arrowhead markers trace directed links, while each edge carries a label along an invisible `path` using `textPath`. Node radius encodes runtime values, and drag behavior allows manual repositioning. The dataset includes 14 nodes and 12 links defined in a separate module.
