What's this kind of multiple scatter plot called?

What’s this called? An array of graphs to visualize relationships between all pairs of a list of variables. The same list of variables appears on the left and bottom edges, and if the list gives five variables, there would be twenty five little graphs tiling the whole space. Graphs on the diagonal are all trivial straight lines, but the rest of the graphs get more or less interesting.

Thanks!!
