DotGraph / Mermaid are not working ?

[jjloesch]

I'm using the example snippet provided in your README.md

dotgraph = """```dotgraph
    digraph "pet-shop" {
        graph [rankdir=LR]
        node [shape=plaintext]
        edge [arrowhead=vee arrowsize=2]
        parrot
        dead
        parrot -> dead
    }
    ```"""
supermd.add_content(text=dotgraph)
supermd.export()

And it only produces and html file with the dotgraph text inside no rendering, same for mermaid.
Did you manage to make it work recently ?
Thank you for your support.
