How can I make my heatmap interactive using Matplotlib?

You can use the mplcursors library to add interactivity to your Matplotlib heatmaps. Would you like a code example?

Yes, please provide a code example!

Here's a simple example:

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
from mplcursors import cursor

# Create some data
data = np.random.rand(10, 12)

# Create a heatmap
sns.heatmap(data, annot=True)

# Add interactivity
cursor(plt.gca())
plt.show()

This will allow you to click on the heatmap cells to see their values.

That looks great! Can I customize the tooltip that appears?

Yes, you can customize the tooltip by using the hover parameter in the cursor function. Would you like to see how?
