Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack.

The matplotlib.pyplot.ion() is used to turn on interactive mode. To check the status of interactive mode one can run the below commands, 

plt.rcParams['interactive']

or, this command

plt.isinteractive()

Matplotlib also interacts with different backends behind the scenes. The workhorse behind rendering charts in Matplotlib is its backends. Some interactive backends dynamically update and pop up to users after every change. By default, the interactive mode is turned off.
