Scatter plot

A scatter plot is a visual representation of correlating data sets.  A scatter plot is similar to a bar or line graph, with a slightly different presentation.  This scatter plot shows how a group of people's weight corresponds to their height.  The scatter plot shows that generally, as height increases, so does weight.  However, there is some outlier data on both ends of the graph.
