How to interpret color intensity in displot?

Question

I am new to seaborn, and I was going through documentation and examples. I have attached the plot below. How can we interpret the color intensity in this plot?

Answer 1

We will not be able to really understand what those bluish colours mean unless there is a scale or a guide which represents the mapping of colors to some attributes of the data.

Thus, the best way to do this would be to add a cbar=True argument in sns.displot, along with the title of the colorbar to make sure the visualisation conveys the context properly.

import matplotlib.pyplot as plt 
import seaborn as sns

penguins = sns.load_dataset("penguins")

sns.displot(data=penguins, x="bill_length_mm", y="bill_depth_mm", cbar=True,
cbar_kws={'label': 'Counts in the bin'})

plt.show()

This gives:
