| FisheyeDistortion | | public class FisheyeDistortion extends Distortion (Code) | |
Computes a graphical fisheye distortion of a graph view. This distortion
allocates more space to items near the layout anchor and less space to
items further away, magnifying space near the anchor and demagnifying
distant space in a continuous fashion.
For more details on this form of transformation, see Manojit Sarkar and

CHI'92, Human Factors in Computing Systems, p. 83-91, 1992. Available
