For comparison to the map, I did a funnel plot of similar data last year, trying to account for the small samples in some counties.


Using ZIP3 should help with the sampling, but doesn't help as much as I would expect with the shape size issue (San Francisco's 940xx is still too small to see until you zoom in). And the speckled look in Iowa comes from discontiguous ZIP3s, forcing a pattern that probably doesn't exist.
