Elaborated Venn diagram


This post displays an example from the Matplotlib documentation. It describes very well the possibilities offered by the matplotlib library in terms of Venn diagram. Thanks to the Matplotlib team for providing such a tool and documentation!

This is an elaborated example of a venn diagram built with matplotlib.

# libraries
from matplotlib import pyplot as plt
import numpy as np
from matplotlib_venn import venn3, venn3_circles
 
# Make a Basic Venn
v = venn3(subsets=(1, 1, 1, 1, 1, 1, 1), set_labels = ('A', 'B', 'C'))
 
# Custom it
v.get_patch_by_id('100').set_alpha(1.0)
v.get_patch_by_id('100').set_color('white')
v.get_label_by_id('100').set_text('Unknown')
v.get_label_by_id('A').set_text('Set "A"')
c = venn3_circles(subsets=(1, 1, 1, 1, 1, 1, 1), linestyle='dashed')
c[0].set_lw(1.0)
c[0].set_ls('dotted')
 
# Add title and annotation
plt.title("Sample Venn diagram")
plt.annotate('Unknown set', xy=v.get_label_by_id('100').get_position() - np.array([0, 0.05]), xytext=(-70,-70),
ha='center', textcoords='offset points', bbox=dict(boxstyle='round,pad=0.5', fc='gray', alpha=0.1),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=0.5',color='gray'))
 
# Show it
plt.show()
