Center and zoom map based on markers

[bnazza]

I want to create a map, add a number of markers, let's say 10 and then have the map center and zoom so that the markers "fill" the map.

The only way I can think to do this at the moment is to calculate the northernmost and southernmost latitude co-ordinates, the easternmost and westernmost longitude co-ordinates and figure a center co-ordinate from there.

Is there an easier way to achieve this in V3?

Have a look at the LatLngBounds object and using map.fitBounds.

My favorite way to achieve this is to include my markers as a KML
overlay. From http://code.google.com/apis/maps/documentation/javascript/overlays.html#KMLLayers:
"By default, when displaying a KmlLayer, the map is zoomed and
positioned to show the entirety of the layer's contents."
