Re: [Orgmode] Need help on org-exp-blocks and dot

[Eric Schulte]

Hi Bryan,

For generating dot graphics from Org-mode it is now suggested to use a
normal code block rather than org-exp-blocks, for example the following
should generate a graph when pressing C-c C-c on the block, and on
export should include the resulting graph rather than the code block.

from http://www.graphviz.org/Gallery/directed/fsm.gv.txt
#+begin_src dot :file fsa.png :exports results
  digraph finite_state_machine {
          rankdir=LR;
          size="8,5"
          node [shape = doublecircle]; LR_0 LR_3 LR_4 LR_8;
          node [shape = circle];
          LR_0 -> LR_2 [ label = "SS(B)" ];
          LR_0 -> LR_1 [ label = "SS(S)" ];
          LR_1 -> LR_3 [ label = "S($end)" ];
          LR_2 -> LR_6 [ label = "SS(b)" ];
          LR_2 -> LR_5 [ label = "SS(a)" ];
          LR_2 -> LR_4 [ label = "S(A)" ];
          LR_5 -> LR_7 [ label = "S(b)" ];
          LR_5 -> LR_5 [ label = "S(a)" ];
          LR_6 -> LR_6 [ label = "S(b)" ];
          LR_6 -> LR_5 [ label = "S(a)" ];
          LR_7 -> LR_8 [ label = "S(b)" ];
          LR_7 -> LR_5 [ label = "S(a)" ];
          LR_8 -> LR_6 [ label = "S(b)" ];
          LR_8 -> LR_5 [ label = "S(a)" ];
  }
#+end_src

Cheers -- Eric
