Last year, the Washington Post released a detailed look into the data leaked by Edward Snowden concerning US intelligence funding. Martin Grandjean used this data to create one simple, overarching graphic, detailing the spending of various intelligence agencies within the US.
For the visualisation, Grandjean used Gephi software, and worked on it in Inkscape. The visualisation shows how the immense $52.6 billion was distributed amongst the US intelligence community, with five main agencies making up the bulk of the spending: CIA (28%), NSA (21%), NRO (20%), NGP (9%) and GDIP (8%).
For more information, please see Grandjean’s original post about the graphic.
