What is GMap?
GMap is an algorithm for visualizing graphs as maps. Information visualization can be invaluable in making sense out of
large data sets. However, traditional graph visualization methods often fail
to capture the underlying structural information, clustering, and
neighborhoods. GMap, provides a way to overcome some of the shortcomings with the help of the geographic map metaphor. While graphs, charts, and tables often require considerable effort to comprehend, a map representation is more
intuitive, as most people are very familiar with maps and even enjoy
carefully examining maps. The effectiveness of GMap is illustrated with
examples from several domains, namely TV shows, Amazon books, and
