Installing Seaborn

To get started with Seaborn, you’ll first need to install it. You can do this using pip. Open your command line or terminal and type the following command:

pip install seaborn

Basic Usage of Seaborn

Here’s a simple example to illustrate how to use Seaborn to create a scatter plot:

import seaborn as sns
import matplotlib.pyplot as plt

# Load an example dataset
tips = sns.load_dataset("tips")

# Create a scatter plot
sns.scatterplot(data=tips, x='total_bill', y='tip', hue='day')

# Show the plot
plt.title('Total Bill vs Tip')
plt.show()
        

Customizing Your Plots

Seaborn allows for easy customization. Here’s how you can change the plot style and add titles:

sns.set(style="whitegrid") # Set the style
sns.scatterplot(data=tips, x='total_bill', y='tip', hue='day')
plt.title('Total Bill vs Tip by Day')
plt.xlabel('Total Bill ($)')
plt.ylabel('Tip ($)')
plt.show()
        

Common Seaborn Plot Types

Some common types of visualizations you can create with Seaborn include:

• Line Plots: Useful for showing trends over time.
• Bar Plots: Good for comparing categorical data.
• Box Plots: Helpful for visualizing data distributions and outliers.
