This example displays a small device network for IoED-Net, with nodes representing network components like sensors, cameras, and routers, and links showing communication lines between them. The layout uses D3’s force simulation, combining `forceLink` to connect nodes, `forceManyBody` for repulsion, and `forceCenter` to center the graph. Node colors follow `d3.schemeCategory10` by group, with labels and links rendered via SVG. The implementation loads D3 v7 from a CDN and uses the `simulation.on('tick')` callback to update positions.
