Babel does support generating diagrams with graphviz via "dot" code
blocks.  Babel is also capable of converting Org-mode tables to list
objects in a number of languages, so I'd recommend writing a table->dot
script in your favorite language, and then using babel to handle the
coordination and Org-mode integration.

I'm happy to help in this regard, the first step would be something like
the following example which assumes python is your preferred scripting
language (as you can see I have no idea what your state table may look

--8<---------------cut here---------------start------------->8---
#+results: state-table
| 1 | 2 |
| 3 | 4 |

#+source: table-to-dot
#+begin_src python :var table=state-table
  python code here

#+begin_src dot :var text=table-to-dot(table=state-table)
--8<---------------cut here---------------end--------------->8---

Once this is working I think it could make a great addition to the
library of babel [1] (a collection of generally useful code blocks).
