After you have created your map, the “Location Data” tab at the bottom of the map will allow you to select the group/s you want to appear. The grouping tool, therefore, also gives you the choice to limit the data shown on your map so that the markers/groups you don’t need won’t clutter your map.
View each group of markers separately, or a few of them together, to suit your purposes, such as for analyzing trends or studying sales numbers within/for a particular group or in comparison with other groups.
You can further customize how you visualize your map by applying the Heat Map feature when analyzing one or more groups or by choosing the Cluster feature to identify a group based on how many markers are within it.
Use the Radius tool to place a circle around a group (or an individual marker) with a defined radius starting from the specified location, i.e., the group or individual marker.
