Styled Google maps or clustering
We needed show or demonstrate several locations on the map which is called clustering. We knew you can do this using Google maps. On the quick video you can see what I mean.
On default it shows the Hamburg, Germany area where most of the Locations (Pins) are. You can also choose what the Zoom level is.
We found a Styled Google Map module which has been at the alpha version since last Christmas but works just great. It uses Views to generate a map so you can quickly generate very flexible and different clusters. It even works together with Display Suite which makes it even better.
Of course you can also change the marker (pin image).
