Shaded low→high on observed fee-for-service services billed from each state · the /stats tile grid, at national scope. Shading ranks the states rather than spacing them along the range, so neighboring shades mean adjacent RANKS, not equal gaps — the key names the lowest and highest; each tile carries its own figure.

Open a state market: AZ · CA · OH · FL — the group ranking lives in the Provider groups tab. Territories bill too; the tile grid draws the 50 states and DC.
