  <p>I want markers to appear in cluster when it have same lat and long ,and when I click the cluster it should zoom in and show the markers.First I was working with agm map.I got an issue when two markers share same lat and long .I used agm-marker-cluster and agm-maker-spider but there was no solution in it.Is there any other way to solve it</p>
