Today we released a new version of the embed movie with new marker clustering functionality. Now, markers are grouped under a circular icon that indicates the number of markers in the group. The group icon is also sized based on the number of markers it contains. This new feature makes it easier to identify groups and visualize their size. Check out the map of the TechCrunch 50 below for an example.
As always, we are looking forward to your feedback on this new feature.

Most recently, UMapper also released a new version of the embed movie with new marker clustering functionality. [...]

I think this is a great feature. We actually creating some maps for motorcyclists in germany, and this feature will help to improve the display of sightseeing points.
PS: Your API is great!
