This is really exciting! I've always liked ggplot2 but sadly struggled with R syntax (the only time I ever used it was for ggplot2, and found it really confusing).
For anyone reading this, I don't think this is intended to replace e.g. matplotlib which I suspect is more powerful overall. It's more for creating good looking, publication-quality graphs. A lot of thought has gone into ggplot2's default theme. A lot of influence from Tufte et al. if I remember rightly. Though, sadly, it looks like this port doesn't replicate ggplot2's graphs pixel-for-pixel, which is a shame.
Edit: Incidentally if anyone has a recommendation for a good graphing app for OS X, I'd be all ears. I still haven't found a good one. I usually use Plot (http://plot.micw.eu) which is great (scriptable, produces good looking graphs) but has a bit of a clunky interface. I personally find DataGraph's interface horrendous, even though its graphs are good, and Excel takes forever to make anything remotely decent. matplotlib and its ilk are fine but require custom scripting. I've been using xmgrace recently simply because it launches quickly, but it's (understandably) not retina and not native and just a pain really. What I'd give for a nice graphing app...
