What are some examples of color maps in Matplotlib?

Matplotlib offers a variety of color maps. Some popular examples include 'viridis', 'plasma', 'inferno', and 'magma'. Would you like to see how to use them?

Yes, can you show me how to apply the 'viridis' color map?

Sure! You can apply the 'viridis' color map using the cmap parameter in plotting functions. For example:

import matplotlib.pyplot as plt
import numpy as np

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

# Create a heatmap with the 'viridis' color map
plt.imshow(data, cmap='viridis')
plt.colorbar()
plt.show()

What other color maps are good for visualizing data?

In addition to 'viridis', you might consider 'cividis' for colorblind-friendly options, 'plasma' for vibrant visuals, or 'coolwarm' for diverging data. Each serves different visualization needs!

Can you explain the difference between sequential and diverging color maps?

Absolutely! Sequential color maps are used for data that progresses from low to high values, like 'viridis'. Diverging color maps, like 'coolwarm', are used for data that has a meaningful midpoint, highlighting deviations from that center.
