This example demonstrates a force-directed network layout using D3.js v5, where nodes are connected by links and positioned through physical simulation. The visualization uses `d3.forceSimulation` with forces such as `d3.forceLink` and `d3.forceManyBody` to arrange the elements dynamically. The code renders a simple SVG-less container with a message div, though the actual drawing occurs in the linked `bundle.js` file. The visualization reads no explicit external data source, instead relying on data defined within the bundled script.
