Approx-Equal a different symbol used in set theory and other mathematical expressions. Python has provided us to use it while plotting.

Following example shows its implementation.

plt.text(0.25, 0.25, r'$\approxeq$', fontsize=175)

Illustrations:

Python code for Approx-Equal symbol in plotting

import numpy as np
import matplotlib.pyplot as plt

# Approx-Equal
# In text
plt.figure()
plt.plot([0,1],[0,1], 'o', color=  'purple')
plt.title('Adding Text: Approx-Equal')
plt.text(0.25, 0.25, r'$\approxeq$', fontsize=175, )
plt.show()

plt.figure()
plt.plot([0,1],[0,1], 'o', color=  'purple')
plt.title('Adding Text: Approx-Equal')
plt.text(0.25, 0.25, r'$\approxeq$', fontsize=175, )
plt.axis(False)
plt.show()

Output:

Output is as Figure
