A graph on a dark blue board. A grey dot lower left and a bright white dot higher up are joined by a dashed pink line. A teal bar runs across from under the grey dot, and a tall orange bar rises from its end up to the white dot, about two and a third times as long. Dotted guides drop to the bottom axis.

The change is the gap between two marks: across 3, up 7. One step across is the same size as one step up.
