It's not new, but thought I'd share this handy tool "StatPlanet" for mapping country-level and sub-national state-level data. It took me half an hour to download and figure out, and then all you have to do is import your Excel spreadsheet in the right format, and it spits out pretty maps. The list of countries with sub-national maps built-in is here. The interactive flash maps are pretty cool too.
