In this chapter, we have learned about Jupyter Notebook and ipywidgets. We also studied how to add interactivity with callbacks in Matplotlib for mouse click and keyboard events.

We learned how to add GUI neutral widgets that work both in the Jupyter Notebook and with any other kind of interactive backend, which is really useful for building applications with Matplotlib. Finally, we learned that animations and movies are very easy to do with simple updater functions that can write out to video files and animated GIFs.
