What would you use to visually represent a correlation?

A) histogram
B) polygon
C) line graph
D) scatterplot

A scatterplot is the best choice to visually represent a correlation as it displays the relationship between two continuous variables plotted as points on a graph, making it easy to observe patterns and trends in the data. A histogram, polygon, and line graph are useful for displaying distributions and trends in single variables, but they do not show the relationship between two variables.
