Open Stack

So it does, I hadn't realized that. The earlier message mentioned using a command-line tool to produce pretty graph images, and I figured I knew just the tool for the job.

Since you're already indirectly using Graphviz, if you're only using PlantUML for processing the output of umlgen.py into a PNG, why not skip a step and generate the Graphviz input file yourself?
Granted, it'll take some work to build a similar visual style--I see elaborate record nodes in your future--but you don't have to be bound to PlantUML if you don't want to be.
I've used Graphviz before for a few applications, and if I can help get you started with building dot files, let me know.

That said, weighing effort against result, you may just be better off sticking with Plant at least in the short term.
I'm sorry I can't suggest a simpler alternative for you right now.

Subject: Re: [openstack-dev] [Murano] MuranoPL => UML visualization <- best implementation practices?

Hi,

GraphViz is alreary used by Plant UML to produce output PNG file, see 'image generation chain' below:
* umlgen.py walks through MuranoPL class(es) and generated temporary file which contains Plant UML definitions for the entire graph
* Plant UML is called with that file as input
* Plant UML processes input file somehow and uses GraphViz to build output image
