I fixed my problem... had to dig around in the source of ob-dot.el, though, since it doesn't appear to be on the website [1]. There are some additional undocumented header parameters that ob-dot adds to the standard Babel params.
With org-exp-blocks you do this: #+begin_dot foo.png -Tpng ... dot code ... #+end_dot With plain old Babel, you do this: #+begin_src dot :file foo.png :cmdline -Tpng ... dot code ... #+end_src Knowing this now, I'd argue for deprecating org-exp-blocks, too. Now my question changes slightly. With the src block configured as above, I can export and execute the code fine, but when I type C-c ' to edit the Dot code in a separate buffer, it goes into fundamental mode, even though I have graphviz-dot-mode [2] installed and working fine. I suspect it might be because it's called "graphviz-dot-mode" instead of just "dot-mode" (that's just speculation on my part, though). Is there a way to explicitly associate an major mode with a particular kind of language block?
