How can one set the rendering control? I'm trying to render graphs with graphviz, but not seeing any options to include the command... apart from that, great idea for a plugin! I use it as a live previewer, while I write in vim.
Thanks for your review. Unfortunately Graphviz rendering is not yet available in a browser environment. A PlantUML extension is under development and might be integrated soon.
Edit: since the last version PlantUML diagrams are rendered ;)
