Drawing a Bubble Chart

Bubble chart can be created using the DataFrame.plot.scatter() methods.

import matplotpb.pyplot as plt
import numpy as np
 
# create data
x = np.random.rand(40)
y = np.random.rand(40)
z = np.random.rand(40)
colors = np.random.rand(40) 
# use the scatter function
plt.scatter(x, y, s=z*1000,c=colors)
plt.show()
 

Its output is as follows −
