First, we need to import a few libraries:

import matplotlib.pyplot as plt
import seaborn as sns


The dataset that we will use is the iris dataset that we can load using seaborn.

df = sns.load_dataset('iris')

Plot multiple elements

With seaborn, we just have to call the kdeplot() function again to add another element to the plot.

Here's how it looks:

sns.kdeplot(df['sepal_width'], fill=True, color="r")
sns.kdeplot(df['sepal_length'], fill=True, color="b")
