Is There a User-Friendly Program for Creating Truth Trees?

[blalien]

I'm looking for a simple program that will create truth trees for me. You see graphics like this (http://upload.wikimedia.org/wikipedia/en/thumb/a/ad/Partially_built_tableau.svg/200px-Partially_built_tableau.svg.png) all the time, but I can't believe anybody would be fiddling around on MS Paint or one of those excessively complicated flow chart programs. Any recommendations? Free is always good.

I don't see that it's too complicated to make such graphs with basic vector graphics editor like http://www.inkscape.org/" .
