I've got a list of hundreds of lat/long coordinates and I want to plot them on Google Maps. What is the easiest way to do this? The data is currently in CSV format.
How do I plot a bunch of points on Google Maps?

I think the easiest way to do this is to create a KML file  with all your lat/long coordinates and open them using Google Earth or Google Maps (http://maps.google.com/maps?q= YOUR KML FILE URL HERE)Some info on creating a valid KML file:http://code.google.com/apis/kml/faq.html#howtocreateand here you can find an Excel to KML converter:http://freegeographytools.com/2007/another-excel-to-kml-converter
