Mildred Bonk

The first map reminds me of the xkcd comic about heatmaps that are really just population maps.


Whenever I see a data set with three dimensions, I look to see if one is a quantity, and another has exactly two categories. If so, voila, scatter chart.


I would have given up some of the demographic data, like the age distribution, to see some information about what the Assembly was doing on various weeks. For instance, were there different issues up for vote that might have accounted for higher turnouts?

Also, since the proportion of outsiders has been introduced into the debate, it would have been nice to see this broken out in the bar chart. Quick mental arithmetic tells me that the percentage of out-of-state residents arrested is pretty low, but seeing it depicted would make it easier. The states of residence of this group is less interesting than how many of them there are.

And, to Mildred's point, plotting some major cities (especially Raleigh) on the map would put the county data in some context.
