Google’s Map API allows for easy creation of custom maps and manipulation of map points with JavaScript. You’ll see in my sample below that you can add points, descriptions, links and control zooming to create interactive mapping on your site.

Longitude and Latitude are required for each map point so either a free geocoding service is necessary for personal use or paid services are available for commercial use.

Aside from the API basics, I’ve modified my sample to zoom in automatically when you click the point, and to zoom back out when clicking on a different area of the map.

Dynamically generating maps from a dataset can be accomplished easily by generating an XML document with latitudes and longitudes.
