Goal Six guesses. Each wrong guess unlocks one piece of metadata — axis label, time range, scope, source.
Guess 1 of 6
How to play
  1. One unlabeled line chart. The axes have no labels and no scale.
  2. Type your guess and submit. Wrong? You unlock one hint — Y-axis label, then time range, then geographic scope, then source.
  3. The chart's shape is the main clue. Most things have a recognizable curve once you've seen a few.
