Drawing pie charts

Let's see how to plot pie charts. This is useful when you want to visualize the percentages of a set of labels in a group.

How to do it…

1. Create a new Python file, and import the following packages:

   import numpy as np
   import matplotlib.pyplot as plt 

2. Define the labels and values:

   # Labels and corresponding values in counter clockwise direction
   data = {'Apple': 26, 
           'Mango': 17,
           'Pineapple': 21, 
           'Banana': 29, 
           'Strawberry': 11}

3. Define the colors for visualization:

   # List of corresponding colors
   colors = ['orange', 'lightgreen', 'lightblue', 'gold', 'cyan']

4. Define a variable to highlight a section of the pie chart by separating it from the rest. If you don't want to highlight any section, set all the values to 0:

   # Needed if we want to highlight ...
