Abstract: A data analysis system (1) for displaying data facilitating visual analysis of communication transaction is disclosed. The system includes a transactions database (3) operable to store transaction records (5) defining communication transactions and a processing module (11) operable to determine a hierarchy having a tree structure wherein leaf nodes in the lowest level of the hierarchy correspond to sources and destinations associated with communication transactions represented by transaction records 5) stored in the transactions database (5).

Abstract: The present invention provides a method implemented by a computer for generating an image on a display that represents a plurality of transactions as lines connecting points in the display indicative of a source and an origin for the respective transactions. For each of the lines, an anti-aliasing process is used to determine a coverage value for each pixel of the display that represents the extent to which the line covers each pixel, and a record of a cumulative coverage value for each pixel is maintained in an image buffer. When the lines have been rendered into the image buffer, the method comprises determining a maximum and a minimum of the cumulative coverage values stored in the image buffer, scaling the cumulative coverage value for each pixel, and rendering each pixel onto the display by using the scaled cumulative coverage value to determine a transparency for the pixel.

Abstract: A data analysis system (1) for displaying data facilitating visual analysis of communication transaction includes a transactions database (3) operable to cause representations of the communication transactions to be displayed on a display screen (13) by determining for each transaction a first set of control co-ordinates; determining for each transaction a set of control co-ordinates for drawing a straight line between co-ordinates associated with the source and destination associated with the communication transaction; calculating as a set of control co-ordinates for representing a transaction weighted averages of corresponding co-ordinates in the first and second set, weighted by a bundling factor; and representing each of the communication transaction as a line drawn utilizing the calculated control co-ordinates for each transaction.
