Visualization with Scatter Plots

This lesson explains what a scatter plot is, why it is used, and how to visualize data with scatter plot using Python libraries.

Introduction to scatter plots

First, let’s take a look at scatter plots.

Scatter plots are great for plotting two variables to visualize how they might correlate and what relationship there might be between the variables.

As an example, look at the scatter plot below.

In this plot, we see a positive relationship between Height and Diameter. It is easy to see that relationship in a scatter plot by looking for points that are close to the 45-degree line pointing up and to the right.
