GeoCommons delivers visual analytics through maps enabling non technocal professionals to view multiple datasets, draw conclusions, make decisions and solve problems witout traditional GIS overhead.  The "Finder!" part of the service is designed to discover interesting publicly sourced datasets through browsing tags and categories, as well as upload, organize and share personally owned data. The "Maker!" part enables the creation of the according online maps, styled with shaded thematics, proportional symbols, graduated icons, points, lines and polygons without any required experience from the user. The so-called "Map Brewer" interface allows users to further classify and slice the data (e.g. quantile, equal interval, standard deviation, maximum breaks), and choose a base map layer (e.g. from Google Maps, Microsoft Virtual Earth, Yahoo Maps or Open Street Map)
