# Visualize Data with a Scatterplot Graph

## Problem Explanation
|
|
|
|
**The Use of a Scatterplot Graph**
|
|
|
|
Scatterplots are a visualization intended for `numerical` data. That is, they display the relationship between one numerical distribution and another. For instance, a scatter plot may be useful in plotting the relationship between number of groceries bought and the total amount paid for them at checkout.

|
|
|
Scatterplots are particularly beneficial in uncovering an association between two numerical variables. Associations can be `positive` (if both variables are increasing together towards high values) or `negative` (while one variable increases, the other's values decrease). If we see some points isolated from the rest, then we can understand that outliers are also present in the data.
