"""Streamlit.

How to use Streamlit in 3 seconds:

    1. Write an app
    >>> import streamlit as st
    >>> st.write(anything_you_want)

    2. Run your app
    $ streamlit run my_script.py

    3. Use your app
    A new tab will open on your browser. That's your Streamlit app!

    4. Modify your code, save it, and watch changes live on your browser.

Take a look at the other commands in this module to find out what else
Streamlit can do:

    >>> dir(streamlit)

Or try running our "Hello World":

    $ streamlit hello

# Set Matplotlib backend to avoid a crash.
# The default Matplotlib backend crashes Python on OSX when run on a thread
# that's not the main thread, so here we set a safer backend as a fix.
# This fix is OS-independent. We didn't see a good reason to make this
# Mac-only. Consistency within Streamlit seemed more important.
# IMPORTANT: This needs to run on top of all imports before any other
# import of matplotlib could happen.
