The Guardian has acquired top-secret documents about the NSA datamining tool, called Boundless Informant, that details and even maps by country the voluminous amount of information it collects from computer and telephone networks.

The heatmap gives each nation a color code based on how extensively it is subjected to NSA surveillance. The color scheme ranges from green (least subjected to surveillance) through yellow and orange to red (most surveillance).
The disclosure of the internal Boundless Informant system comes amid a struggle between the NSA and its overseers in the Senate over whether it can track the intelligence it collects on American communications. The NSA's position is that it is not technologically feasible to do so.
