They've changed the threshold for how light blue, blue etc. are picked. First map, light blue is 1-620. Second map, light blue is 1-949. The red starts at 2961 in the first map, 3769 in the second. IOW the red "hot zone" is not comparable to the red in the first map. One of these maps on its own would show you the rankings among counties, but comparing the maps is highly misleading.
Counties that were red in the first map can fall out of red in the second map, even if they have increased transmission. If the parameters were kept the same there would be more red counties in the second map.
Yes the thresholds were changed. But that may be just the default distribution for the map program. It doesn’t mean that it’s nefarious.
The question I would ask is who is showing that graph to whom and why? It’s a heat map of counties — which are doing better and which are doing worse per 100k of population. If it’s just one out of several standard graphs that get issued issued every week, I have zero issue with that. If it’s like that Mis-ordered data that Georgia showed when they first opened up, then obviously that’s a ridiculous misuse of numbers.
IIRC, when they first opened the state, they showed a chart of daily cases, which some moron had re-sorted, rather than showing the days in calendar order.
