Do you like open data? Do you like visual representations? If so then you should give Freebase a look. With Freebase, visitors can use all types of publicly available data to create "entities" which will be connected and manipulated into a graph format. Freebase has access to about 13 million entities, so interested parties have a tremendous amount of material to choose from. Visitors can use the material on the homepage to see what previous users have done with this data. This version is compatible with all operating systems, including those running Linux.
