9. Drawing Histogram and Pie chart using Matplotlib

 from matplotlib import pyplot as plt

import numpy as np

# Histogram chart

marks=[90,50,40,60,55,44,45,10,34,84]

grade_interval=[0,30,50,60,70,90]

plt.title("STUDENT GRADE")

plt.hist(marks,grade_interval)

plt.show()

# Creating dataset using pie chart

cars = ['AUDI', 'BMW', 'FORD','TESLA', 'JAGUAR', 'MERCEDES']

data = [23, 17, 35, 29, 12, 41]

# Creating plot

fig = plt.figure(figsize =(10, 7))

plt.pie(data, labels = cars)

# show plot

plt.show()
