Update zipcode map
The zipcode map is almost useless when all zips are same color. Need to change granularity so you can identify zips with >100, >500, >1000, etc.

While the granularity has been fixed, incorrect shading has been introduced, probably due to a character sort instead of numeric sort of the descriptions for the shading:
Incorrect:
lighter 1-10
darker 101-500
darkest of 3 11-100The darkest of the 3 categories listed should be 101-500, but the darkest is 11-100. It gives a completely wrong visual interpretation. Click on several zip codes with medium shading and you will see many, many darker zips with only 20 or 30 cases and lighter zips that have 200 to 300 cases. It really needs attention and prioritization.
