Graphviz markdown extensions

I have enabled several extensions to my pelican website.

One that I wanted to include was graphviz. So, I searched for one and while I found a few, they somehow, did not work for me.

So I wrote my own: mdx_graphviz.

It is quite straight forward. You just need to create blocks:

dot {
    digraph G {
        Earth [peripheries=2]
        Earth -> Mars

You can use this Graphviz Visual Editor for a more interactive approach.
