Abstract:
This paper presents a fast and efficient
focus+context technique, called DualView for navigating
large graphs/hierarchies which are usually displayed in
a high-density manner. The DualView includes two
transformations: a browsing and a fisheye-like
distortion. The browsing transformation is responsible
for interactively exploring large hierarchies with a highresponse
rate and inexpensive computational cost. On
the other hand, the fisheye-like viewer increases the
degree of distortion of the image by increasing the
original magnification function which is created by the
browsing transformation. This dual enlargement enables
users to see the detail of any interested area in a highdensity
visualization.
