An interface is provided on a computing device for interacting with data stored in a data repository. Input is received including information identifying two or more attributes, and information indicating an order for the identified attributes. A hierarchical data structure is stored, with an order of hierarchy levels corresponding to the indicated order. Multiple attribute values for the attributes are determined. The method includes assigning to each node of a first level at least one of the attribute values of a first attribute, and assigning to each node of a second level at least one of the attribute values of a second attribute, each of the nodes of the second level also being assigned respective ones of the attribute values assigned to one or more nodes of preceding levels. The interface is displayed including displaying interface elements associated with each of the nodes. |
