1. A graphical visualization system for analyzing and graphically representing a correlation of a plurality of transaction items occurring within a physical locality, the system including: a processor device; a memory device; a display device; a graphing module executable by the processor in communication with the graphical visualization system arranged to graphically represent on the display device the physical locality, the graphical representation including a graphical representation of a plurality of locations within the physical locality; a data retrieval module executable by the processor arranged to retrieve data stored on the memory device from a data storage module in communication with the graphical visualization system, the retrieved data including information on the location of the items within the physical locality, wherein the retrieved data is associated with the transaction items; a dimension module executable by the processor arranged to correlate the transaction items in a dimensionally reduced manner using the retrieved data, and further arranged to graphically represent the correlated transaction items as a graphical overlay over the graphical representation of the physical location, the graphical overlay of the correlated transaction items and the correlated transaction items being linked; a hierarchical tree module executable by the processor and arranged to create a tree hierarchy using the retrieved data, wherein the tree hierarchy is arranged to classify the transaction items in a hierarchy according to a defined user understandable factor, the hierarchical tree module further arranged to graphically represent the tree hierarchy, the graphical representation of the physical location, the graphical overlay and the graphical representation of the tree hierarchy all being displayed in a combined graphical representation, wherein the graphical overlay, the graphical representation of the tree hierarchy and the correlated transaction items are linked; and an interaction module executable by the processor arranged to graphically represent in the combined graphical representation an interaction between the correlated transaction items and at least one transaction item in the graphical representation of the tree hierarchy by i) detecting a selection in one of the graphical overlay, graphical representation of the tree hierarchy and the graphical representation of the physical locality and ii) graphically representing how the graphical overlay, graphical representation of the tree hierarchy and the graphical representation of the physical locality are linked, wherein the interaction module is further arranged to highlight the link between the selected graphical overlay, graphical representation of the tree hierarchy or the graphical representation of the physical locality and the linked non-selected graphical overlay, graphical representation of the tree hierarchy and the graphical representation of the physical locality in the combined graphical representation.
