Versioned graph
This example shows how to visualize the evolution of a graph across multiple versions, using a hierarchical layout with explicit layer / siblingIndex placement and a data-driven diff mode to highlight added and removed elements between two cumulative snapshots.
Pick a "Visible version" to see the cumulative graph at that point in time. Enable "Show diff" and pick a "Compare version" to color nodes and edges by their diffState (added, removed, common).
