Your implication is correct that the CDC chart is mostly incomparable to the OP. The chart tries to combine incomparable data, which annoyingly requires interpretation of the legend to understand correctly.

The circles indicate nucleocapsid (i.e., infection only) while the squares indicate spike (i.e., infection or vaccination).

So, Puerto Rico is 70% infected and/or vaccinated (a square). Whereas NY is 13% infected (a circle).
