Topic on Extension talk:Diagrams/Flow

Hello. I try to render a simple uml diagram, but get an error:

Diagrams error (with plantuml command): /bin/bash: line 1: plantuml: 
command not found

I've downloaded latest archive, extracted it and added line into LocalSettings.php.

Am I missing anything? Should I install any other additional software?

Well, one should install plantuml and graphviz as separate packages. Diagrams is just a wrapper for these tools in mediawiki. Now everything works fine.
