Similarity Matrix

This map was taken from http://tomcat.esat.kuleuven.be/txtgate/tutorial.jsp

This is a good example of a similarity matrix.  This matrix allows the viewer to see how similar two data points are to each other.  In this example, the points that are closer to red are more similar and the points that are closer to green are less similar.  Obviously the diagonal line is all red because these are where the data points are exactly the same.
