Well, I *now* know it's not described in the Org manual...

Though, it's described in many different posts on this ML, and in some
tutorials on Worg...

I thought it was a "core" option value for all general-purpose languages (e.g.
emacs-lisp, python, R, ruby, sh), required when your code block outputs a
graphics.
After checking, I only found it in those files:
--8<---------------cut here---------------start------------->8---
./ob-maxima.el:117: (and (member "graphics" (cdr (assq :result-params params)))
./ob-octave.el:272: (and (member "graphics" (cdr (assq :result-params params)))
./ob-R.el:234: (and (member "graphics" (cdr (assq :result-params params)))
--8<---------------cut here---------------end--------------->8---
Maybe they are the only general-purpose languages able to output graphics? No,
wait, your example shows that python is also able to do so.
Then, I don't understand what that ":results graphics" option is not part of
python. Sorry not to be of more help...
Best regards,
Seb
