This paper presents a new multi-level focus+context technique for visualizing and manipulating hierarchies which contain large number of leaves. Our technique uses an ordinary 2D Hyperbolic Tree Browser to display the major structure of hierarchies while a 1D distortion-based fisheye menu is also used to assist the display of those sub-hierarchies containing large number of leaf nodes. This significantly solves the problem of inefficient use of the display space when a user navigates, using a Hyperbolic Tree Browser, through a portion of the hierarchy containing a large number of leaves.
