I have nodes with locations.
Now i want to add a small map with a pin for the location.

Ok, i can do that. the map will center on the pin, and i can set the default zoom level.

But i want to center&zoom the map to a region (country x, continent x) the node belongs to.

I thouht a way could be to add a geofield with bounds, and one with the location's lat/long.
Then tell the map to zoom to the bounds and show the marker at location.

But i did not manage to get that working, even thought i searched, read and experimented for...
rather days than hours with gmap, openlayers, leaflet etc.

Any hints?
