Using clustering in grav-plugin-leaflet?

Hi hughbris,
I hope that I do not mix it up. The way I have noted different points/marker is:

[map-leaflet lat=10 lng=0 zoom=2 mapname=test style=test]
[a-markers icon=""]
[{ "lat": 20.8, "lng": -159.7, "text": 49 },
{ "lat": 18.3, "lng": -173.3833, "text": 32 },
{ "lat": 19.4667, "lng": -174.5833, "text": 52 },
{ "lat": 16.75, "lng": -176.4, "text": 50 },
{ "lat": 19.0333, "lng": -177.3167, "text": 46 },
{ "lat": 32.5833, "lng": -132.5, "text": 50 },
{ "lat": 0.6667, "lng": 169.2833, "text": 79 }
....
]
[/a-markers]
[/map-leaflet]

Or do you mean differently styled markers like shown here?

Is that any help for helping me? :=)
