Otherwise, I think the possibility of offering various variants in one diagram is very effective.
It is especially effective for 'combinatorial cases'. With 8 armies you would need 64 Diagrams to provide all combinations. The number of buttons required is 4 times smaller, and buttons are again much smaller than Diagrams. I suppose one could even do with 8 buttons here, using the convention that clicking the buttons alternately defines white and black.
