Importing or Exporting GraphViz .dot Files

OmniGraffle OmniGraffle for iOS

Is it possible to import GraphViz .dot files into Omnigraffle for iOS?

That would make programmatic generation of diagrams feasible.

I gather Omnigraffle for iOS (and for Mac) embeds the GraphViz engine.

Rather secondarily I’d be interested in exporting to .dot format.

Gosh, this is an old one of mine.

It DOES work but a test yesterday suggested it wasn’t 100% on the shapes of nodes. I can supply the test data.
