Scatterplot



-A scatter graph or scatter plot is a type of display using Cartesian coordinates to display values for two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis.

- The screen shot below shows the scatter plot for Birth rate and Population growth rate and associated cross classification map. You can see that the items selected by mouse dragging (shown in the pink box) are highlighted with black boundary lines on the map of Europe.
