Hi,
I really like the idea of writing graphviz .dot code in Texmacs
and getting the Graph directly embedded in the document.

So I try executing dot code in a Graphviz session, like for example:

digraph G {
        node_0 -> node_1
}

which always produces the following output:
<error|bad image|null box>

The full, directly out of the session copied source of a example
(it contains a <image|<tuple|<#252...0A>|ps>||||> tag which could be relevant), is readable here:

Since there is absolutely no Documentation for the plugin, neither shipped with Texmacs nor findable in the www,
I have absolutely no clue what I am doing wrong.

So what's the mistake, how is the Graphviz plugin to be used ?
