First user-generated input is received that selects a first element in a graphical user interface identifying a work area. In response, a plurality of second elements characterizing categories of objects associated with the work area are displayed in the graphical user interface. Thereafter, second user-generated input is received that selects a second element in the graphical user interface element. Once the second element is selected, a visual representation of a plurality of primary objects associated with the category corresponding to the second element is displayed. The plurality of displayed primary objects are displayed in a first person perspective projection format with the objects being displayed in order at depths in the first person perspective projection according to values of an attribute associated with the second element. Related apparatus, systems, techniques and articles are also described.
