How to annotate seaborn pairplots?

To annotate Seaborn pairplots, we can use the fig.text() method.

Steps

Import Seaborn, Pandas, Numpy, and Pyplot packages.
Set the figure size and adjust the padding between and around the subplots.
Create a Pandas dataframe of two-dimensional, size-mutable, potentially heterogeneous tabular data.
Plot pairwise relationships in a dataset, using sns.pairplot().
Add an annotated text using fig.text() method.
To display the figure, use show() method.

Example

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

plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

df = pd.DataFrame(
   np.random.random((4, 4)),
   columns=["a", "b", "c", "d"]
)

pp = sns.pairplot(df, height=1.5)
pp.fig.text(0.5, 0.5, "My Pairplot",
   color="green", fontdict=dict(size=20))

plt.show()

Output

It will produce the following output
