feasible region

Two quantities on the axes, each hard limit as a line, and the surviving area shaded. The shape of the region is the finding: a fat region means slack, a sliver means one more constraint kills the plan, and no region means something has to give.

Example

Best when you have two or three numeric limits and want to see whether any plan satisfies all of them.
