Document Summary

In spite of all the technical development and the obviously attractive features. 3d graph visualization techniques have still significant difficulties: the main reason lies with the inherent cognitive issues of using 2d screens and. 2d input devices to interact with a 3d world: perceptual and navigational conflicts arise due to this discrepancy. The hyperbolic layout of trees is one of the recent forms of layout (lamping et al. and. Developed with visualization and interaction in mind. It provides a distorted view of a tree layout it resembles the effect of fish-eye lenses. It can be implemented in either 2d or 3d. The distorted view makes it possible to interact with large trees. Hyperbolic views are radically different, due to their different geometrical background. It is suitable for some demanding real-world applications. Layout algorithms alone cannot overcome the problems raised by the large sizes of the graphs occurring in many applications. Zoom and pan are conventional tools in visualization.
