Unexpected-judgement map for one judge (pair level)

The judge counterpart of the kidmap, drawn matchup by matchup. Each pair the judge met is a segment on the consensus location axis, spanning its two objects, positioned horizontally by how surprising the verdict was: at zero (the dashed line, inside the shaded band) the stronger object won as its lead predicts; to the left the judge backed the underdog. A filled dot marks the object the judge's verdict favoured, hollow the other – so an upset is a red segment on the left with its filled dot at the lower end. The rug marks every object's location.
