This example demonstrates a minimal force-directed graph layout with three nodes and two links, rendered using D3.js version 6. It uses `d3.forceSimulation` with `d3.forceManyBody` for repulsion and `d3.forceCenter` to position nodes, while a `tick` event handler logs updates to the console. The graph is defined as static arrays of nodes and links, with no visual output yet, as the circle positions remain commented out. The code currently focuses on simulation setup rather than rendering the network.
