Yaccviso visualizes yacc and bison grammars. It will generate a .dot or .vcg file that you can play around with in graphviz (from AT&T research labs fame) or VCG. The graphics above shows a very simple version of the very same yacc grammar which was used to write Yaccviso. Is is especially helpful when you have a large grammar file. Yaccviso will show you the dependencies between the grammar's left hand side (LHS) and its corresponding RHS non terminals and terminal symbols. It just helps to visualize! This is especially true when you have to keep in mind the first- and follow-sets.
