Get tutorials working on colab

[faroit]

👋 @flekschas as part of the JOSS review I wanted to try jupyter-scatter myself and started with these notebooks. I found that they didn't seem to run out-of-the-box on colab for me, though.

• [x] a hint on the package installation is missing in the notebook itself (e.g. !pip install ...). I know this makes the notebook look less clean so the alternative would be to store colab-specific versions on google instead of running them from this repo.
• [x] without a specific hint about the package name, users might be inclined to install jscatter instead jupyter-scatter from pypi. Furthermore, there is a general clash in package naming for these two projects, so maybe a hint on the project website would be helpful
• [x] after installing jupyter-scatter the notebook runs, but no widgets are shown even for the simpliest example below. Is there some specific configuration required to make inline rendering work? (I tried %matplotlib inline but that didn't help).

import jscatter
import numpy as np

jscatter.plot(x=np.random.rand(500), y=np.random.rand(500))

@faroit Good points! I'll add install instructions for Google Colab to the notebooks.

Regarding point 3, could you provide more details? I just tried it and everything works as expected. Did you by chance accidentally installed jscatter first? I noticed that uninstalling jscatter and then installing jupyter-scatter does not work in Google Colab. I had to start a new session.

@flekschas regarding the third point, it's true that it works fine when running installing in a fresh kernel so that was my mistake of installing the wrong package first. But maybe that also emphasizes the importance of mentioning the package name clash somewhere.

@faroit I've added pip install instructions to the notebooks via https://github.com/flekschas/jupyter-scatter-tutorial/pull/5. I've also added a note about the install instruction to the README. Does this address your other concerns?

@flekschas excellent. Thanks a lot!
