Guess at default layouts

[hadley]

So you can start with ggraph(graph)

Oh you just need layout = nicely() as the default?

I've contemplated about this and I'm frankly torn. On one hand the required call is currently a bit verbose, on the other hand I really dislike setting defaults for so important arguments. My main fear is that users would think the default is almost always the right choice (it almost never is) and never explore alternate layouts...

[hadley]

You could make it print a message? People tend to like quiet code so that would provide a (small) push to explore the options?

[thomasp85]

That might be a good idea...
