Yep, both Marpa-style grammars and Set::FA::Element-style state transition tables can now be graphed.
As always, the demo page is the place to start.
After that, hit CPAN.
It is nice that you have that demo page. Could you also link from each image page to the source code and data used for that examples?
Oh and you know, that you can embed links in your pod so that these images will show up on search.cpan.org? For example see Chart::Clicker
In the POD for GraphViz2, under Synopsis, I have a link to the demo images.
And I have often thought of putting the test data on-line. That's why I decided on a policy of keeping the data in files, instead of - as I started out doing - putting it in the __DATA__ section. So, I'm getting there.
As it is, each demo has a comment near the top, which is used to build the index page. I can expand that, or scan the code looking for the name of the data file. For that, I'd use Pod::Simple and the code_handler feature, which I already use for GraphViz2::Parse::ISA.
The pieces are almost all in place...
I try to write all code in Perl, but find I end up writing in bash, CSS, HTML, JS, and SQL, and doing database design, just to get anything done...
