What are Seaborn pairplots and how do I use them?

Seaborn pairplots are a way to visualize relationships between multiple variables in a dataset. They create a grid of scatter plots for each pair of variables, along with histograms or density plots on the diagonal. You can use them to quickly identify correlations and distributions.

Can you show me an example of how to create a pairplot?

Sure! Here's a simple example using the Iris dataset:

import seaborn as sns
import matplotlib.pyplot as plt

# Load the Iris dataset
iris = sns.load_dataset('iris')

# Create a pairplot
sns.pairplot(iris, hue='species')
plt.show()

What does the 'hue' parameter do in pairplots?

The 'hue' parameter allows you to color the points in the scatter plots based on a categorical variable. This helps in visualizing how different categories relate to each other across the variables.

Can I customize the appearance of the pairplot?

Yes, you can customize the appearance by using parameters like 'palette' for colors, 'markers' for different point styles, and 'diag_kind' to choose between histograms or kernel density estimates on the diagonal.
