What are some examples of heatmaps using Seaborn?

Can you show me some examples of heatmaps using Seaborn?

Sure! Seaborn is a powerful visualization library in Python. A heatmap is a great way to visualize data in a matrix format. Would you like to see a specific dataset example?

Yes, I'd love to see an example with a correlation matrix.

Great choice! You can create a heatmap of a correlation matrix using the sns.heatmap() function. Here's a simple example:

import seaborn as sns
import matplotlib.pyplot as plt
import numpy as np

# Create a sample correlation matrix
data = np.random.rand(10, 12)
correlation_matrix = np.corrcoef(data)

# Create a heatmap
sns.heatmap(correlation_matrix, annot=True, cmap='coolwarm')
plt.show()

What does the annot=True parameter do?

The annot=True parameter adds the numerical values of the correlation coefficients to each cell in the heatmap, making it easier to interpret the data.
