PNG format is perfect for the web. It is a lightweight format that is often used for websites.
But be careful, it comes with a transparent background, which nowadays can be annoying if you have a dark theme.
Anyways, here is how to save a Matplotlib plot in PNG format.
# For our example dataframe
import pandas as pd
# For our plot
import matplotlib.pyplot as plt
# Generating sample data
df = pd.DataFrame({"col1":range(10)})
# Creating a figure and the axes for our plots
# We set the figsize to 12 inches wide and 6 inches tall
fig, axes = plt.subplots(1,1, figsize=(6,4))
# We plot
axes.plot(df["col1"])
# We make our canvas tidy and clean
plt.tight_layout()
# We save the graph in png format
plt.savefig("my_graph.png")
