import matplotlib.pyplot as plt
 
x_coordinates=range(-20,20,1)
y_coordinates=[x*x for x  in x_coordinates]
plt.plot(y_coordinates,x_coordinates)
plt.show()
 
Explanation: In this program we are importing pyplot class  from python. pyplot library is part of matplotlib library. matplotlib is used to create mapping functionality and different types of Maps, graphs and charts. this library is used for various reporting, analytics and dashbaording functions.
 
x_coordinates variable is storing range object for x axis plotting points on graph. y_coordinates is getting all y points for plotting  against x points range. plot function of pyplot object plots the points using corresponding range objects. plt.show() function shows the graph on screen.
 
It is a example of simple graph equation y=x2 . This way we can plot any graph equation.
