●Radar chart
A “radar chart” is used to compare and balance multiple elements.
For example, this chart shows the balance between scores a student received on tests in various subjects.
“Correlation” refers to a relationship between two properties such that as the
value for one increases, the other decreases. When the relationship between
these two is nearly linear, the two properties are said to be correlated.

●Scatter diagram
A “scatter diagram” plots two property values on the X- and Y-axes to
show the correlation between two kinds of data.
For example, the positive correlation graph plots volume of cold beverage
sales against temperature, showing that as temperature increases, sales of
cold beverages increases. The negative correlation graph plots hot beverage sales against temperature, showing that as temperature increases, sales
of hot beverages decrease. The no correlation graph plots magazine sales
against temperature, showing that the two are not related.
