Lightning (http://lightning-viz.org/) is a pretty cool interactive visualization server, with clients that work across multiple languages/environments. I've used it with R and Python and it's pretty slick.

I'm always a bit disappointed that yhat indiscriminately used 'ggplot' for the python package name. Using a variation on the name would have been more considerate.

I tried a few years ago and found that it didn't implement much and didn't work correctly. Since then I usually use something like rpy2 to run standard ggplot2 from Python.

Hopefully it has improved.

matplotlib makes fantastic plots, it's just not a very nice API.

Seaborn is quickly becoming my favourite and a bit more similar to ggplot in terms of scope.
