**What it does**

This tool outputs a graph representing the tree, either as text or
as a SVG or PNG image. Underscores in labels are replaced with spaces.
Trees with no branch lengths are taken to be cladograms and are
drawn with leaves aligned. Otherwise, the tree is assumed to be a
phylogram: branch lengths are honored and a scale bar is drawn.
