This is interesting. I have to say that for all the power that Python has in the scientific community, and scientific computation in particular, visualization has a long way to go. There are charts I made 5 years ago in C++ using a framework called ROOT that was much prettier. ROOT was only maintained by a couple of people at the time. This was particle physics.
I use both frequently. The real thing I like about root is the ability to interactively change the style of the plot itself by opening it in the editor. Saves a lot of time, better than having change one line of code and recompile just because a label is off by a few pixels
