Hi R users

I am looking for a command or function that draws a graph based on a correlation matrix or any lower or upper diagonal matrix.

If I have 5 variables (X1, X2, X3, X4, and X5) there are 10 unique correlation values

I like to draw some kind of a gird graph based on these values, using (1,2) (1,3), (1,4), (1,5), ...., (4,5) as positions on the graph. If a correlation value is closer to 1 then the color for the value is getting black. If a correlation value is closer to zero then the color for the value is getting white.

Is there any graphic package allowing for doing that ?

TM.
