What's the Challenge With Altair?

One of the things that can be a little tricky with Altair is behind the scenes, it's translating whatever data you have into a JSON file. So rightly so, Altair, make sure that you don't inadvertently embed that in your notebook. But you could end up with your Jupyter Notebook suddenly being 50 megs because you've got all these Altair visualizations in there. There are some options for how you can manage that data so that it's not necessarily stored directly in the notebook file.
