recommendation: The map uses color to provide information about the number of records. This issue is not as detrimental as it could be because of the alternative way the information is provided (kudos!), but it should be noted. Users with color blindness or who may have another vision impairment, may not be able to understand or perceive the differences between the colors on the map.
