This demo shows how to use the snapping feature to support editing a radial tree
layout.
The snapping feature provides snap circles for all children around their parent and snap
lines for the most important angles. There are also some snap lines to align sibling nodes
on a circle.
Snap circles and lines will only appear for the direct parent and siblings of the moved
node.
Things to Try
Move a leaf node and place it anywhere on the same radius. A snap circle will appear for
visual support.
Move a node to the top, left, bottom, and center and snap it to the predefined angles
and on the circle.
Move a node opposite to one of its siblings and align both nodes.
Move a node between two of its siblings and place it centered between them.
