Venn Diagram

⏱ Quick start

The venn2 function of the matplotlib_venn library is the best way to make a Venn Diagram with Python, as shown on the code below.

Note that several input formats are possible to get there. This first post of the section goes through them and should get you started from any kind of input. 🔥

Most basic Venn Diagram with Python

# library
import matplotlib.pyplot as plt
from matplotlib_venn import venn2

# Use the venn2 function
venn2(subsets = (10, 5, 2), set_labels = ('Group A', 'Group B'))
plt.show()

Venn Diagram with Matplotlib and matplotlib-venn

Matplotlib is probably the most famous and flexible python library for data visualization. It is appropriate to build any kind of chart, including the lollipop plot thanks to its stem() function.

Venn Diagram with 3 sets.

Customize Venn Diagram: circles, lables and more.

Change Venn diagram background color.

The Venn2() function allows to customize the venn diagram as much as you want, allowing to build some pretty neat figures as below:

The matplotlib-venn library allows a high level of customization. Here is an example taking advantage of it

Upset plot as an alternative

Venn diagrams are great to visualize the intersection between 2 or 3 sets. Above that they become quite messy and unreadable.

There is a alternative to them: the upSet plot that can be made thanks to the upSetPlot library
