Very nice article. But who else thinks the arrows should be drawn the other way? In his diagrams, they indicate depends on. I think it would be more natural to draw them in the direction of the data flows - which cell each cell supports. That way the computation is visualized running in the direction of the arrows, rather than the reverse direction.
