Abstract: A computer-implemented method may include displaying, on a display device, a graphical diagram with multiple graphical objects that represent data of a data source. The method may include overlaying a legend on the graphical diagram, the legend including one or more legend data objects associated with a set of graphical objects of the graphical objects, each set of graphical objects including a common graphical attribute among the set of graphical objects. Additionally, the legend data objects may be configured to be user-interactable, where, upon interacting with a given legend data object, the set of graphical objects associated with the given legend data object are all selected such that by interacting with the given legend data object, all of the members of the associated set are interacted with.
