Triangulation
Coverage against case burden
Vaccination coverage as fill, confirmed cases as bubble area — so states with high burden and low coverage stand out as large bubbles on pale ground.

The correlation is descriptive, not causal. These are cross-sectional observational counts, cases are reported by state of residence rather than place of infection, and testing intensity varies by state — so a state with more cases may simply be testing more. 9 states have no vaccination data and are excluded from the comparison entirely.
Overlay
Coverage and burden on one map
Bubble area is proportional to case count, scaled by square root so Lagos does not swamp every other state.

Coverage and cumulative incidence
The same overlay with bubbles sized by cumulative incidence — cases as a share of each state's population — so large states no longer dominate by size alone.

Cases against coverage by state
Bars are case counts, rings are coverage. States are ordered by case count, so a low ring above a tall bar marks a high-burden, low-coverage state.
