Abstract: A computer assisted system and method for the visualization, manipulation and analysis of data, in which a computer-assisted data visualization and analysis session undertaken by an analyst, including all intermediate and final data visualization, manipulation and analysis steps and functions, are electronically archived on a computer-readable medium and instantly made available to authorized collaborators so that authorized collaborators may review all the intermediate visualization, manipulation and analysis stages. Any authorized collaborator may choose any intermediate or final data visualization stage and commence a new, but related data visualization, manipulation and analysis derivative session. All derivative sessions, including all intermediate and final data visualization, manipulation and analysis steps and functions are archived and published to authorized collaborators.
