TL;DR

I discovered PlantUML, a program to generate a lot of different graphs, UML and not.

From time to time I find it useful to generate Sequence Diagrams, i.e. images like this:

Some time ago I used sdedit, a nice tool that has the great advantage that the diagram is entered as text describing the different interactions.

Lately I needed it, only to… not remember the name. So I asked the mighty internet, and PlantUML came out.

It’s really nifty, gets the inputs as text too, and has a lot of examples for sequence diagrams. So I thought… better write a bit about it, so that future me will have an easier time finding it again!
