Plant UML

Please refer to http: plantuml.com do get full description of the PlantUML syntax.

With PlantUML, you can draw:

sequence diagram,
use case diagram,
class diagram,
activity diagram,
component diagram,
state diagram,
object diagram.

A typical PlantUML diagram is enclosed by ''@startuml'' and ''@enduml''.  Replace these by ''<uml>'' and ''</uml>''.

This block:

<uml>
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
</uml>

renders this:

There is also a toolbar button that is added to quickly add the tags into the page.

Syntax

Whatever is inside the uml tags will be displayed as a SVG on the wiki page:

<uml>
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
</uml>
