[UX] main_RecordVariable - Improve tutorial by indicating how to run the script Python
Context
I was following the tutorial for the "Record Variable" branch, but when I wanted to display or save the data collected, I didn't know how to do it properly.
Problem
I didn't know the steps needed to run the script when using Visual Studio Code.
Idea of a solution
Add a few steps in the tutorial to indicate the packages needed for the script and how to run the python script to plot the data or save it in a file.
