Previously when viewing the Bulk Event Report via a MAP, there could be potentially thousands of markers all put over each other on the same map.
Now, with clustering, it will display the number of entities in the same area if they are too close together, and then if you select it, it will zoom in until you can see them as separately selectable dots, which you can click to see information about the entity (e.g. the meter); and navigate to it on the Object Dependencies screen.
