**[MermaidJS](https://mermaidjs.github.io/)** was my favourite cool thing in 2018!

But I can't find a way to draw MermaidJS `graph` or `sequenceDiagram` on Stack Overflow.

I've seen many Markdown tools such as [StackEdit](https://stackedit.io/app#), [Typora](https://typora.io/), [Markdown Plus](https://mdp.tylingsoft.com/) and [Markdown Monster](https://markdownmonster.west-wind.com/) support MermaidJS, and I feel a little bit restricted not having the luxury of this cool technology on Stack Exchange sites.

Adding `<!-- language: mermaid-js -->` or triple back-ticks (````mermaid`) didn't work so I assumed it is not supported.

I think this would be very useful in asking design-related questions, or in explaining complex scenarios.

So will it ever be supported? if not, what are the alternatives?
