There's no rule that says that the first dimension must be rows and the second must be columns.

True, but myself I tend to prefer the array of two-valued arrays structure myself. I think of the inner arrays as "points", i.e. pairs of (x,y) values, and typically you want to do things like push/pop points from your collection of data.

But then it all depends on how the original poster is going to be graded -- I mean, on the details of the OP's application.
