Organisation D3 Network
This example demonstrates a minimal force-directed network graph using D3 version 7, depicting three nodes (Alice, Bob, Carol) connected by two directed links. It initializes a simulation with `d3.forceSimulation`, applying `forceManyBody`, `forceLink`, and `forceCenter` to position the nodes. The code logs each simulation tick to the console, but does not render any visual elements beyond an empty body with a "Hello D3 version 7" text message. The network structure is defined as static JavaScript arrays, and the example relies on D3’s modular imports from the `d3` package.
