Correlation

This widget displays data in a scatter plot. A scatter plot is a graphical representation of two numerical variables plotted along two axes. This graph can be good when you want to identify or show the relationship between two variables.

This graph displays the correlation between the number of ordered items and the order size. The grouping by countries reveals that Norway has bigger and more valuable orders than the other countries.
