                   10.  Using Matplotlib and the given data, plot a bar chart:

                       No of people voted = [23,45,31,40,35]
                       Area covered = [‘a1’,’a2’,’a3’,’a4’,’a5’]
                  Ans.  Program:

                      import matplotlib.pyplot as plt
                      No_of_people_voted = [23,45,31,40,35]
                      plt.bar(['a1','a2','a3','a4','a5'], No_of_people_voted)
                      plt.title('Bar Chart')
                      plt.xlabel('Area covered')
                      plt.ylabel('No of people voted')
                      plt.show()
                      Output:
                                                                     Bar Chart

                   11.  Using Matplotlib and the given data, plot a line chart:

                      x_axis = [3,4,6,2,8]
                      y_axis = [9,10,8,7,6]
                  Ans.  Program:

                      import matplotlib.pyplot as plt
                      import numpy as np
                      x = np.array([3,4,6,2,8])
                      y = np.array([9,10,8,7,6])
                      plt.plot(x, y)
                      plt.show()
