The Notebook Server
If you’re already familiar with Jupyter notebooks:
Skim the section on how to login to the Nevis notebook server (if you’re at Nevis).
ROOT takes a slightly different approach to drawing plots in a notebook.
No matter what, read the section on JSROOT. It will introduce you to ROOT’s interactive plots within notebooks.
If you’re not familiar with Jupyter or IPython, welcome! I’m going to introduce you to a different software development tool. It’s independent of ROOT, but it can be handy for creating ROOT programs.
