For quite simple trees(Up to 50 nodes should work OK) I've used 'dot'
from the free graph visualization software GraphViz [1] which takes an
ASCII file describing the nodes and edges of a graph (or tree as
special case) and produces Postscript besides other
formats. Unfortunately this solution does not allow you to
interactively expand and collapse subtrees with mouse clicks, if this
is what you really want.


I've also seen the GNU program 'info' or HTML being used to view a
parse tree.
