A monoid for generating tree diagrams

render a tree diagram as a function that prepends a multi-line string

print a tree diagram

draw a value as a simple, single-line tree diagram

>>> printTreeDiagram $ singleton 'a'
'a'

Move a tree diagram to the subtree level, dropping a line down from the graph line to connect it to the new toplevel.

>>> printTreeDiagram $ subtree (singleton 'a') <> singleton 'b' <> subtree (singleton 'c')
 ┌─'b'─┐
 │     │
'a'   'c'
>>> printTreeDiagram $ subtree mempty

>>> let d = singleton 'a' <> subtree (subtree (singleton 'b') <> singleton 'c')
>>> printTreeDiagram d
