There are a number of different ways to graph the values of a matrix. Which is best will depend on what you want.

You could try:

ListDensityPlot[matrix];
ListContourPlot[matrix];
ListPlot3D[matrix];

Or if you want a graphical representation of the matrix structure, try

<<<< LinearAlgebra`MatrixManipulation`
MatrixPlot[data];

or

<<Statistics`
PairwiseScatterPlot[data];

Note, this last was introduced in Mathematica version 5
