Any programs that helps to draw Expression trees?

Question

I am trying to draw a expression tree with some algebraic tree. I drew that in paper but now I need to draw that in computer. Is there any program that lets me draw expression tree.

I was trying to use microsoft word but found it extremely painful.

Any suggestions will be highly appreciated.

It looks like graphviz may be the answer to your problems. I've only really used it in "batch" mode, to generate GIFs of parse trees and elaborate process flows, but I think you're talking about parse trees when you saw "expression tree".
