Snapping
This demo shows how to enable snapping (guide
lines) for graph elements. This is provided through class
GraphSnapContext.
Snapping helps you to arrange graph items interactively without running an automatic
layout by providing useful lines and position hints that elements snap to.
In addition to this, labels with certain label models can snap to particular positions
relative to their owner, for example to the corners of a node or along the edge path. This
can be enabled with class LabelSnapContext.
