Scatterplot

 

http://onlinestatbook.com/chapter4/pearson.html

Scatterplots are similar to line graphs in that they use horizontal and vertical axes to plot data points. But  scatterplots show how much one variable is affected by another. They usually consist of a large body of data and the closer the data points come when plotted, the higher the correlation between the two variables, or the stronger the relationship. The scatterplot above demonstrates the correlation between how close a wife and husbands ages are.
