Mermaid on Github Examples

All of these diagrams are dynamically rendered during html display by Github, the images generated from text inside the Github-Flavored Markdown. None are static images. Mermaid support was released for Github on 2022-02-14

Pros & Cons:

Pro: You don't need to care about the layout.
Con: You cannot control the layout.

Notes:

Not all the features of Mermaid (in particular symbols B-->C[fa:fa-ban forbidden], hyperlink and tooltips) are supported by Github.
