**[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][1], [Typora][2], [Markdown Plus][3] and [Markdown Monster][4] 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?
