I would like to make a TikZ diagram to show the detailed dependency structure of the theorems in my thesis with nodes and subnodes. Ex:
Theorem 4 (A) coding theorem (A1) proof techniques (A1a) converse (A2) Theorem 5 (B)
and then indicate that there is a dependency
(A1a) --> (B)
which is more precise than saying that Theorem 5 depends on Theorem 4. More specifically, this is what I am trying to draw:
Is there a TikZ package for that? Or for drawing .deb dependency graphs?
I found one package/framework for course prerequisites: http://www.texample.net/tikz/examples/prerequisite-chart/ but the underlying format is very low level so you are meant to edit with a program.
All advice / example / recommendations will be much appreciated!
