Representation of several customers in a map with geolocalization

Hi all,
is there a simple way to obtain a chart with “several” customers geolocalization in a map without the needing to write tons of code ? There are many applications that do it with only giving coordinates and maybe few parameters. I’ve seen a video but it’s a mess of coding that I would like to avoid.
On geolocalization maybe it would be nice , on mouse click, to see for istance some values related to customer like turnaround, credit situation and other info.
Many thanks

I would use the Google maps api
