Maptable is a Javascript library for displaying tabular data on a Google Map, complete with data filters, customized icons, legends, and info balloon templates. Maptable also makes it easy to add WMS imagery overlays (and KML files and GeoRSS feeds) to your map.

Maptable provides a new Javascript function maptable(map, options) that adds features to your map based on the configurable options.
