Support roadmap diagram

[hukacode]

Hi there,

I searched all issues on this repo but I did not find anything to draw this similar diagram.

Do we support to draw like that? Many thanks for considering my request.

Best regards, Huka

I am curious as well if things such at that can be done with mermaid.

Also would like to see that functionality in Mermaid, thank you!
