Pandas: Visualization Integration Exercise-8 with Solution

Write a Pandas program to create a pie chart using Pandas and Matplotlib.

This exercise shows how to create a pie chart using Pandas and Matplotlib to visualize the proportions of categorical data.

Sample Solution :

Code :

import pandas as pd
import matplotlib.pyplot as plt

# Create a sample DataFrame
df = pd.DataFrame({
    'Category': ['A', 'B', 'C', 'D'],
    'Values': [30, 25, 20, 25]
})

# Create a pie chart for 'Values' by 'Category'
plt.pie(df['Values'], labels=df['Category'], autopct='%1.1f%%')

# Add a title
plt.title('Category Proportions')

# Display the plot
plt.show()

Output:
