A staircase, not a curve. Between two rungs there is no model, so a smooth line would invent options that do not exist. Chartreuse marks the undominated set. Each graphite dot has a model that scores at least as high, costs no more, and wins on one of the two. Logos name the vendor; they are not a ranking colour.
