it looks about right until the very end; Manually running "dot /tmp/babel-2749DTL/dot-2749Nkt -Tpng -o /home/matt/example-diagram.png" from a shell works fine. However, the result of:

(org-babel-eval
     (concat cmd
         " " (org-babel-process-file-name in-file)
         " " cmdline
         " -o " (org-babel-process-file-name out-file)) "")

is "nil". Any idea why that might be?

Just a quick addendum. Pausing during debugging and running

(with-temp-file in-file )
(org-babel-eval
"dot /tmp/babel-2749DTL/dot-2749Nkt -Tpng -o /home/matt/example-diagram.png" "")

from a scratch buffer also works. So I am really confused -- maybe there is something wrong with ob-dot itself?

Again, many thanks,
Matt
