Thanks for the great software!
It would be great if I could sneak in some Graphviz syntax in my PlantUml diagram. E.g.
@startuml
component foo : graphviz=[style="radial"]
component bar : graphviz=[image=bar.jpg, width=120px]
foo --> bar : graphviz=[arrowtail="onormal"]
foo --> bar : graphviz=[style="invis"]
