An apparatus and method are described herein that provide for visualizing subsets of grouped business objects in an application for display in a user interface. Business objects are grouped into subsets according to a selected business object attribute value. The business objects are grouped and displayed in a three-dimensional view including a plurality of layers, where each layer represents a subset of the business objects. The application is implemented, for example, as a calendar application. The visual representations associated with the business objects in each subset of data are displayed in each of the layers of the three-dimensional view. A user selectably controls which subset of data to view in the user interface.
