Nice! I was just looking to convey entity diagrams to a client - and thought of doing them through something like Omnigraffle - this looks like it could do the job.
However - it doesn't seem to export itself well (the Print doesn't work - or something like a read only link would be enough)
There is a read only link, that’s what the demo is. Under the drop down for the diagram (hovering the diagram name in the top center), you can find a Presentation Mode. Then just share that link.
