Abstract: A method for efficiently presenting and allowing rapid navigation of data on a computing device may include generating at the computing device a graphical user interface including a static layout, the static layout including a display region and a first level interaction region for a first level, the display region configured to display data representing one of a second level subgroup and a third level item, and the first level interaction region having a plurality of sub-regions; receiving a user input; determining whether the received user input is a selection of one of the plurality of sub-regions of the first level interaction region; in response to the determination that the received user input is the selection of one of the plurality of sub-regions, updating the display region to include the second level subgroup corresponding to the selection of the one of the plurality of sub-regions; determining whether the received user input is a selection of the display region; and in response to the determination
