We’ve added a new feature that’s automatically turned on when mapping large sets of locations, pie chart clusters. These graphics make it easy to spot trends and hot spots in a quick glance. The pie charts are created and sized automatically based on the number of markers in a given area, the more markers, the larger the pie chart.

Additionally clicking on the legend will cause the map to filter results down to just the selected group, updating the pie charts dynamically. To enable pie charts on your map, just select a group column and turn on the clustering feature (both under advanced options.) Please let us know your feedback on this new feature by posting comments below.
