Can you pass custom properties to graphviz? #994

Closed mbwgh closed 8 months ago

mbwgh commented 10 months ago

I am trying to use the ordering attribute, which does not seem to be among the supported properties. I haven't found an obvious extension point after having spent some time looking at the docs and stepping through the code.

Is it possible to attach such a custom property to a node, in a way that it will be picked up by the graphviz layouter (I guess in the end DotExporter.java) and passed to graphviz?

Hi, ELK uses an old version of graphviz, I do not know if this option is even supported. If I remember correctly, the implementation in ELK does not allow passing new options to graphviz, sorry.
