A multi-ownership tree-map visualization system can include a tree-map configured to visualize a set of interrelated nodes in which at least one individual node in the set is related to at least two parent nodes in the set. The system further can include an event handler programmed to process a proximity event associated with a specific portion of the tree-map by highlighting multiple portions of the tree-map in which the portions represent a single node in the set. In this regard, the proximity event can include a mouse-over event, a mouse-click event, or a keyboard selection event, to name a few. The system yet further can include logic for displaying a call-out box for each portion of the tree-map associated with the single node in the set.
