Abstract
Social networks link people together, among which a lot of factors
influences their complexity. To our understanding, so far most visualization
interfaces for social networks have not reflected any of their factors. Therefore,
this paper tries to solve such a problem by rectangular cartograms, which is a
kind of geographical visualization interface using rectnaguls to represent
regions in a map. Besides the relative position of each rectangle can reflect the
actual geographical related positions, one of the main feastures of rectangular
cartograms is that the area size or the shape of each rectangle can reflect the
information of its corresponding region, e.g., the population in that region. This
paper proposes a layout approaph for rectangular cartograms with area labeling
for social networks, in which each region has a minimum-width constraint for
accommodating a text label. As a result, this paper applies a genetic algorithm
to finding the area-labeling rectangular cartogram with minimum width under
some constraints to meet the practical use in social networks. By doing so, we
can visualize the labeling text on each rectangle and observe the information
represented by its area size or shape at the same time. Furthermore, the
proposed approach is applied to visualizing the distribution of the Facebook
popularity of an enterprise in Taiwan. From the cartogram, the text label on
each region can be read directly and the relation among regions as well as the
popularity can be visualized, so that the enterprise can improve the regisons
with poor popularity by the help from the regions with high popularity.
