This example demonstrates an interactive directed layout where users can push and pull nodes within a continuously updating force-directed graph. Selected nodes remain fixed while other nodes are automatically repositioned through a custom `ContinuousForceDirectedLayout` that extends GoJS’s `ForceDirectedLayout`, reusing the layout network for performance. The visualization uses GoJS for diagram rendering and D3.js v7 for utility functions, with node dragging triggering layout invalidations to animate the graph in real time.
