Pareto frontier

Every candidate plotted against two goals you both want. The outer edge, where no point is better on both, is the frontier. Points inside it are dominated: some other option beats them on both goals, so they can be dropped without regret.

Example

Best when there are many options and two goals in tension, and you want to discard the ones that lose on both.
