Bar plot

Bar plots are the graphs that use bars to compare different categories of data. Bars can be shown vertically or horizontally, based on which axis is used for a categorical variable. Let's assume that we have data on the number of ice creams sold every month in an ice cream parlor over a period of one year. We can visualize this using a bar plot.

Before we plot the graph, we need to import the necessary packages:

import matplotlib.pyplot as plt
import numpy as np
import calendar
