Hi,
You got lots of responses but I want to defend the TikZ option.
There's a very helpful group of users on the mailing list so you're
not alone with the 248-page manual:
https://lists.sourceforge.net/lists/listinfo/pgf-users
If you're doing a lot of these diagrams, a solution within TeX is
going to speed up your workflow a lot. You can copy-and-paste code
to make new diagrams from old diagrams. If you decide to change
styles, you can do it in one fell swoop. And the language itself is
very well suited to exactly the kind of diagrams you want to make.
You can create and name "nodes" and draw arrows between them.
