Google today released Google Fusion Tables in Labs. Fusion Tables allows users to upload more data than they can in Google Spreadsheets. With Google Fusion it is possible to upload tabular data sets of up to 100 MB per data set.

One visualisation tool for Fusion Tables is a Google Maps view of any geo-location data that you have in your table. Currently there are a number of data sets already shared in Google Fusion that have Google Maps views. These tables can be viewed by anybody with a Google account. The shared tables include global child mortality rates, a global climate change projection, Academy Awards by country and total renewable freshwater supply by country.
