Installing on my Mac to test this out was very straight-forward:
cd /tmp
mkdir streamlit
cd streamlit
pipenv shell
pip install streamlit
Then I could play with the built-in demos by running: streamlit hello
So that was a slick intro - next step was I followed this tutorial: https://streamlit.io/docs/tutorial/create_a_data_explorer_ap...And a few minutes later I had an interactive notebook-style interface for playing with Uber pickup data in New York.
This is a really interesting product.
