8. A computer system comprising: one or more processors which process program instructions; a display device; a memory device connected to said one or more processors; and program instructions residing in said memory device for evaluating plural results of an analysis performed by a cognitive system by generating a visualization of the plural results on the display device, the visualization including a plurality of primary graphical elements representing confidence levels for the plural results, result labels proximate the primary graphical elements, and a plurality of secondary graphical elements visually associated with a particular one of the primary graphical elements wherein the secondary graphical elements represent secondary data associated with a particular one of the plural results corresponding to the particular primary graphical element, the secondary graphical elements being presented in the visualization in a condensed form where each secondary graphical element is only partially visible, detecting that the particular primary graphical element has been selected, and transitioning the visualization by moving the secondary graphical elements to an expanded form where each secondary graphical element is fully visible.
