• pip install matplotlib
• pip will take care of dependences itself so you don’t need to get worried about it.

Graph

• You first need to import the package after installation by import matplotlib.pyplot as plt.

• There is a inbuild funtion to plot the graph plot() which will take many arguments but I am passing two arguments x and y coordinates.

x = [x1, x2,x3]
y = [x4, x5, x6]
plt.plot(x, y)

• Read more about plot function here @https://matplotlib.org/users/pyplot_tutorial.html

• To display the graph you need to use show() function

• plt.show()

• It will plot a line graph with above coordinates

• There are few more parameter in plot() funtion so let discuss about that

plt.ylabel('Population in million')
