Hello Ivan, Thanks for bringing Graphviz to Haskell, and for your continuing dedication to making it more complete!
I just tried Graphvis for the first time a few days ago. I regretted the absence of example code, especially as the API has been evolving, so that examples on the Web do not generally work without change. I see that the inclusion of QuickStart-style documentation is on your short-term list of milestones. I suppose an example program is not quite that, but it might help. Do you have something along these lines? Or, if not, if I managed to put something together which exercises a good cross-section of the features, do you think you could include it with the next release? I suppose there's a trade-off between ease of maintaining the code through releases, and feature coverage of the example(s)... I'm CC-ing haskell-cafe in case anyone reading already has some example code like this, which they'd be willing to donate? If possible, it ought to be small yet illustrate a lot of features.
