This example demonstrates an interactive force-directed graph built with GoJS, where users can push and pull nodes in real time while a custom ContinuousForceDirectedLayout continuously recalculates node positions. The layout keeps selected nodes fixed while moving others, and it caches the force network for efficiency, invalidating it only when the model changes. Nodes appear as blue circles with text labels, and links include directional arrowheads with semi-transparent label backgrounds. The example also includes a minimal D3.js message display using `select`, showcasing integration with ES6 modules.
