Examples do not work in the jupyter notebook

[lbignone]

Very interesting mini module. Thank you for this.

Examples do not appear to work in the jupyter notebook. I had no problem executing them in the ipython shell

Here is the traceback (Jupyter 5.0.0, python 3.6.1, ipython 5.3.0):

@lbignone - thanks for the report, I hadn't tested it yet in the notebook. Can you provide the code you used to get the above traceback?

[astrofrog]

@lbignone - I found the issue and am fixing it in https://github.com/astrofrog/mpl-scatter-density/pull/8

[astrofrog]

@lbignone - I've merged the fix and released v0.2. Can you confirm that this is now fixed for you?

[lbignone]

I can confirm all examples in the README work in my notebook
