Using MarkerClusterer in map view

Can anybody help me figure out how to implement MarkerClusterer with Scheduler Map View?

I’m confused as to how to call it within dhtmlxscheduler_map_view.js. I’m aware that all I need to do is add:

var markerCluster = new MarkerClusterer(map, markers, options);

But it doesn’t seem to be working. Can anyone point me in the right direction?
