Geographical display of current call volume within the contiguous United States of America. Each call is represented by a node of "heat", therefore a large amount of calls comprises a larger concentration of heat. You can select the play button to display call volume for the previous 2 hours from your present time. You can also zoom in and out of the map, allowing you to focus-in on "high-heat" areas. This module may assist you in identifying problem areas (reflected by a "hotspot" on the map with high call volume).
