Wow! The excellent online thematic map software Indiemapper is now free.  Unfortunately, this decision appears to go hand in hand with one to reduce future development – which means we aren’t likely to see easy excel integration anytime soon (always a drawback in my mind).  The features that are there, however, are beautifully integrated. The method for assigning classed and unclassed color ranges using an interactive histogram, for example, should be a model for other software; and the ease with which you can switch map projections is almost magical.
