: As you have locations, the result may be an interactive map. Open-source interactive map software are not very numerous, but you can generate static images and then assemble them in an animation.

A great combination of software is R + python + FOSS GIS (free and open source, like GRASS or QGIS). Some introductory educational content are listed here : www.osgeo.org/educational_content
As a professional cartographer, i was asked recently to create an on-line visualization tool of quantitative values spatialized as points, over time, and i used the GeoExt lib, a bridge between Sencha's Ext.JS web framework and OpenLayers mapping framework, but it's perhaps a bit complicated.
