This example shows a force-directed graph network of organizations, where nodes are colored circles connected by lines and sized by importance. The visualization uses D3 v6 with the `forceSimulation`, `forceManyBody`, `forceLink`, and `forceCenter` APIs to compute the layout physics, and the `drag` interaction allows nodes to be repositioned. Circle positions and link coordinates update on each simulation tick, and the data appears to be loaded from static node and link arrays generated from a local source.
