This visualization shows the weights of connections between nodes in a small network using a force-directed layout. It uses D3's `forceSimulation` API with `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide` to position nodes, where link distances are proportional to the provided weight values. The nodes render as green circles with purple labels, and the links are drawn as dark lines. The dataset is hardcoded, and the code includes drag interaction through D3's `drag` method.
