Scatter plot

http://en.wikipedia.org/wiki/Scatter_plot

A scatter plot is a mathematical diagram that uses Cartesian coordinates to display values for two variables for a specific data set.  Scatter plots provide a useful summary for a set of bivariate data and can be used to determine what kind of relationship there might be between the two variables.  The scatter plot above displays the waiting time between Old Faithful Eruptions as well as the eruption duration.
