This example visualizes a force-directed simulation of labeled nodes and links, where node positions are influenced by both collision detection and a centering force. It uses `d3.forceSimulation` with `d3.forceCollide` and `d3.forceCenter` to compute the layout, while `d3.select` and `transition.attrTween` animate the node elements as the simulation steps. The data is embedded within the code as a static array of node objects and link references, and the rendering relies on standard SVG circles and lines. The simulation runs continuously, updating positions each tick.
