This example shows a small force-directed network of three nodes and two directed links, with each node labeled by its name and rendered as a circle. The visualization uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to compute positions, and d3 selection methods to create SVG circles, text, and lines. Data comes from a static JavaScript module defining nodes and links, and updates occur on each simulation tick, adjusting coordinates of all elements.
