"Top Secret America" [washingtonpost.com] is an extensive investigative project of the Washington Post that describes the huge national security buildup in the United States after the September 11 attacks. More than a dozen Washington Post journalists spent 2 years developing the database, which was put together by compiling hundreds of thousands of public records of government organizations and private-sector companies. From these records, The Washington Post identified 45 government organizations (for example, the FBI) engaged in top-secret work and determined that those 45 organizations could be broken down into 1,271 sub-units (for example, the Terrorist Screening Center of the FBI). At the private-sector level, The Post identified 1,931 companies engaged in top-secret work for the government, ranging from the "nuclear operations" by AT&T to the "cyber operations" of Abraxas.
The project also seems to put the newspaper on the data-visualization-as-journalism map, still dominated by the New York Times infographics department.
The "Top Secret Network of Government and its Contractors" explores the relationships between government organizations and the types of work being done in "Top Secret America". A radial table can be rearranged according to 3 questions: "Who does the most types of work?", "Who works with the most companies?" and "Who does which types of work?" The data can be further filtered along several categories, such as Intelligence, Military or Weapons Technology.
The "Where is Top Secret America?" shows the locations of government organizations and companies that deal with security (although stops short explicitly naming them?). One can also query for specific companies, or search the data for themselves.
