Andrew J. Kennedy wrote a functional pearl describing how to draw a tree
in "aesthetically pleasing" way[1]. His code is written in SML, and the
output isn't ready-to-display image, but you can take the idea and use
some GUI toolkit (GTK seems most ready-to-use, but I may be terribly
wrong) to draw the image in window.
