Hello everyone, 

I try to implement an example of an graphviz diagram in asciidoc and i get the following error: 
Failed to generate image: Could not find the 'dot' executable in PATH; add it to the PATH or specify its location using the 'graphvizdot' document attribute

this is my example:

["graphviz", "dia.png"]
----
digraph automata_0 {
  size ="8.5, 11";
  node [shape = circle];
  0 [ style = filled, color=lightgrey ];
  2 [ shape = doublecircle ];
  0 -> 2 [ label = "a " ];
  0 -> 1 [ label = "other " ];
  1 -> 2 [ label = "a " ];
  1 -> 1 [ label = "other " ];
  2 -> 2 [ label = "a " ];
  2 -> 1 [ label = "other " ];
  "Machine: a" [ shape = plaintext ];
}

----

I have set the environmental variable GRAPHVIZ_DOT and the path GRAPHVIZ_HOME. I'm not sure why I'm still not able to get an image.

I use Windows.

Thank you in advance.

The message says Asciidoc can't run graphviz executables.

You did install graphviz and it works from the command line?

As the message above says, set the document attribute `graphvizdot`,
not environment variables.
