Mermaid Demo

TLU can now support mermaid diagrams! Flowcharts, sequence diagrams and more!

How to write mermaid diagrams.

RTFM.
Wrap your mermaid code in <div> tags. Add the class=mermaid attribute to the tag. So your code will look like


<div class="mermaid">
graph LR
...
</div>

Note: You can't have blank lines in your diagrams, unfortunately, because the markdown renderer will interpret this as a new paragraph and break your diagram. However, you can sort of workaround this by putting a # as a spacer (see first example).

Sequence diagram example


<div  class=mermaid>
sequenceDiagram
    Alice ->> Bob: Hello Bob, how are you?
    Bob-->>John: How about you John?
    Bob--x Alice: I am good thanks!
    Bob-x John: I am good thanks!
 #
    Note right of John: Bob thinks a long<br/>long time, so long<br/>that the text does<br/>not fit on a row.
    Bob-->Alice: Checking with John...
    Alice->John: Yes... John, how are you?
</div>

Flowchart example


<div  class=mermaid>
graph LR
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
</div>

Gantt Chart example


<div class="mermaid">
gantt
       dateFormat  YYYY-MM-DD
       title Adding GANTT diagram functionality to mermaid

       Future task               :         des3, after des2, 5d
