This demo shows an experimental way of displaying a hierarchical diagram using ZUI (Zoomable User Interface). In this approach, we define each level as a separate diagram and when the user zooms in on the container, we dynamically replace the contents of the diagram with a child diagram. Conversely, when the user zooms out of the container, we replace the current diagram with the parent diagram and only display images of the child diagrams inside the zoomable elements. Thus, a detailed view of the diagram is obtained by simply zooming in.
