Abstract

Data navigation of a treemap—a widely used tool for visualizing tree data—becomes more difficult as the amount of data increases. To solve this problem, treemap techniques using zoomable user interface (ZUI) methods—the most typical of which is the zoomable treemap (ZTM)—have been proposed. However, ZTMs can incur face text overlapping issues between examined nodes. In order to increase ZTM readability, we propose a label embedded tree map technique that prevents label overlapping and a direct node selection method for the highlighting of focused parent nodes. The proposed tree map technique resolves the ZTM label conflict and the direct node selection method can efficiently improve data navigation.
