How do I interpret the symbols in the maps of county-level estimates?
In the dot-density maps (i.e., maps showing the number of adults), the symbols used represent the different levels of the scale. The smallest dots represent the lowest level of the scale whereas the largest dots represent the highest level of the scale. In the bivariate maps (i.e., maps showing percentage by number of adults), small to large squares of different colors (blue, orange, red) were used to represent the gradation of the percentage of adults with diabetes by the total number of adults with diabetes. For example, for all indicators, the small blue squares indicate the lowest percentage of adults by the lowest total number of adults. On the other hand, the large red squares indicate the highest percentage of adults by the highest total number of adults.
