[x3d-public] Repairing this Jupyter Notebook is a pain!

[Vincent Marchetti]

I forgot to mention that the rendering of an .ipynb file on the github page can garble the markup.

A more reliable way to see the notebook as a static rendering is to use the nbviewer page:

https://nbviewer.org/github/vincentmarchetti/web3d2021_jupyter_tutorial/blob/main/HelloWorld.ipynb

to see this HelloWorld style example of putting an X3D scene in a Jupyter notebook
