I've spent the last couple of days trying to code this but haven't yet succeeded. Any offers?
(NOTE: I'm looking for a compact dump to a terminal; not presentation quality graphics here. Ie. I'm not looking for GraphViz or similar, so please don't tell me about those.)
Hmmm. I've seen something resembling that in Tree::Visualize, I'm sure the BOX-ing can be easily undone ... Tree::Visualize::ASCII::BoundingBox ... here is a start
See also http://stackoverflow.com/questions/801740/c-how-to-draw-a-binary-tree-to-the-console which appears right on the money but I've not tested it
I really am surprised there isn't something in the GraphViz family to do this already, graph-easy can read DOT files but the output isn't exactly what you want
