31. An article of manufacture comprising a storage medium containing instructions that when executed enable a system to: generate a multivariable decomposition visualization to present hierarchical information for a response variable and multiple reporting variables defined for the response variable in a single user interface view, the multivariable decomposition visualization comprising multiple graphical user interface (GUI) elements each representing a reporting variable value of multiple reporting variables for multiple hierarchical levels, with a GUI element of a reporting variable value of a reporting variable of a hierarchical level selectable for decomposition into multiple GUI elements representing reporting variable values of a different reporting variable for a different hierarchical level; receive a control directive indicating selection of the selectable GUI element of the hierarchical level for decomposition into decomposed GUI elements of the different hierarchical level; and present the selectable GUI element of the hierarchical level adjoining with the decomposed GUI elements of the different hierarchical level in response to the control directive.
