Building A Spider-chart With Turtle Or Tkinter

I recently did 2 beginner courses in python coding at university for my Minor, which were followed by an intro to databases and a basic course about CRUD development in PHP. The py

Solution 1:

You can construct a radar, or spider chart with tkinter.

The following class takes a list of tuples('label', score), with the score expressed as a percentage (value in the interval [0, 100]).

The number of data points adjusts to the data provided. The scale of the chart can be adjusted.
