This might be an issue isolated to my system/install, but I had a missing module after following through the tutorials in order, using Jupyter Lab and Pixi.
The command gglot(terns) in section " 3.2.2. Layer 1: Data " had a missing module: pyarrow
I had added all other prerequisites (to my knowledge) from Python Basics 1-3 prior to that point, but kept getting an error. Not a major issue.
