Head to head
Each row is named for the thing more of which is better, so a longer bar always wins.
Longer is better. Bar length is the rank among all 453 cities we hold that measure for, not a share of the pair.
Profile shape
Outward is better on every spoke, on the same percentile scale as the bars above. The area is not a score: it moves with the order of the axes.
Every metric, side by side
Each row carries the level it is measured at. A country figure is never printed as a city figure.
