Euler's diagrams are non-empty Venn's diagrams. For further information about:

Motivation

How to install

We run the command on desired installation environment:

pip install eule

Minimal example

Click to unfold usage

We run command python example.py on the folder with file example.py and following content:

#!/usr/bin/env python
from eule import euler, euler_keys, euler_boundaries, Euler

sets = {
    'a': [1, 2, 3],
    'b': [2, 3, 4],
    'c': [3, 4, 5],
    'd': [3, 5, 6]
}

euler_diagram = euler(sets)
euler_keys = euler_keys(sets)
euler_boundaries = euler_boundaries(sets)
euler_instance=Euler(sets)
