Scatterplot

http://www.netmba.com/statistics/plot/scatter/
A scatterplot shows the relationship between two variables by plotting data points on a two-dimensional graph. This generic scatterplot shows the basic format for a scatterplot. Notably, it lacks a trend line, which is a line used to show the average of points along a plot. Such a line is often used in lieu of the actual data points on graphs in order to simplify or hide outliers and/or weak relationships in the data.
