The location of the dot is abstract and not based on geography. Instead, dots with edges between them are pulled closer together. This produces a series of clusters, which are labelled by the words that are most "characteristic" of the reports in that cluster.
It's mapping 3,051 nodes (26.3% of 11,616 documents), connected by 106,660 edges, and 17,608 terms. The highest incidence (44,61%) relates to criminal events, with enemy action (29.47%) and explosive hazard (16.72%) following behind.
