Graphviz Support

I have spent some time adding Grapviz support to my blog. Now I am able to write graph descriptions directly in markdown instead of separate .dot files.

I can write something like this:

~~~ {.dot-render}
digraph G {
    graph [bgcolor=transparent];
    a -> c;
    b -> c;
    c -> d;
}
~~~

And you will see something like this:

And while it could have been done in a simpler manner, I hope to reuse the code for some other stuff…
