Any idea when Mermaid diagrams will render outside of web browsers?

<rant> Aside, I'm the author of KeenWrite (https://keenwrite.com/), a Markdown text editor that allows embedding diagrams using the triple-backtick syntax. Here's a GraphViz example:

    ``` diagram-graphviz
    digraph {
        rankdir="LR";
        a -> b -> c;
    }
    ```

In Markdown, formatting a source code snippet entails using the standard syntax for code blocks:

    ``` graphviz
    digraph {
        rankdir="LR"
        a -> b -> c;
    }
    ```
