I got this simularity matrix from http://tomcat.esat.kuleuven.be/txtgate/tutorial.jsp. This type of map is helpful in gene mapping and in determination of particular organisms.

This is an example of a random correlation matrix. These are common in scientific studies. There are two triangles in a correlation matrix
but that would be redundant to add since they are mirror images of one another.
