I've created an activity diagram with swimlanes in plant uml the diagram travels from top to bottom but I want to make it travel left to right. I found this answer about PlantUML different layouts but it does not seem to apply to activity diagrams. And when i tried to apply "left to right direction" to my diagrams there were errors.
Example code
@startuml
|Swimlane 1|
start
:Do something;
|Swimlane 2|
:Do something;
stop
@enduml
Diagram that I want to travel from left to right instead of top to bottom.
