The point is, that I would like to make an app using Google Maps, but I have to add more than 100 thousand markers and I would like to show them this way (video below), what I mean is, when I am zooming more and more markers appear.
You could make markers visible in comparison to the zoomlevel.
If zoomlevel = 15 then generate markers etc etc.
If you would like to have numbers in markers then you have to use custom markers and that is not possible at the moment. That is something i hope will be added.
