Deep Zoom Demo
This demo allows you to seamlessly zoom into the contents of deeply nested group nodes,
similar to what is known as "deep zoom" for images and maps.
The graph component does not display the complete graph but only the nesting level that
fits the current zoom level. That means that graph items at a higher nesting level are not
rendered at all, and the contents of group nodes that are too small to provide meaningful
interaction is displayed as a static image. When zooming in on such a group node, this
image is eventually replaced with real graph elements.
Things to try
a group node so that its entire contents fill the current viewport, and observe that the
displayed graphic is automatically replaced by the contents of the group.
of a group and observe that its previous nesting layer becomes visible and the content
of the group becomes an image again.
to exit all groups and reset the zoom.
