Creating a Pie Chart with Pandas and Matplotlib
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:
Explanation:
- Created a DataFrame with categories and their values.
- Used plt.pie() to create a pie chart that shows the proportions of each category.
- Added labels and percentage annotations (autopct='%1.1f%%') to the chart.
- Displayed the pie chart with a title.
