This example shows a simple three-node organization graph, displaying relationships between individuals as circles connected by lines. The diagram uses a force-directed simulation to position the nodes and links dynamically. It is built with D3 v7, specifically using `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to handle layout, while SVG elements are bound to the data and updated on each simulation tick. The graph moves and settles into a balanced arrangement, though the current code only demonstrates a chain of connections without labels or additional styling.
