UnlabeledTree

[Experimental]

✖

returns a tree of the same shape as tree in which the nodes and edges are displayed without labels.

Details and Options

  • UnlabeledTree shows the overall structure of a Tree object.
  • By default, UnlabeledTree gives a tree with Null as the data of each node.
  • If the original tree has options, they will be modified to eliminate labels in the output.
