A bubble plot is very similar to a scatterplot. Using matplotlib library, a bubble plot can be constructed using the scatter() function. In the example, the following parameters are used:

  • x : The data position on the x axis
  • y : The data position on the y axis
  • s : The marker size
  • alpha : Transparancy ratio
# libraries
import matplotlib.pyplot as plt
import numpy as np
# create data
x = np.random.rand(40)
y = np.random.rand(40)
z = np.random.rand(40)
# use the scatter function
plt.scatter(x, y, s=z*1000, alpha=0.5)

# show the graph
