GVSR: An on-line guide for choosing a graph visualization software It is easy to find graph visualization applications for all sorts of uses. However, choosing an appropriate application may be difficult. This poster presents a website (url{http://gvsr.polytech.univ-nantes.fr/}) built to help users to choose a program adapted to their problems. So far, this site references eighty programs and aims at helping users both in their choices and in comparing the programs. The site is also designed as a tool repository helping the community to access and compare the available tools, and benchmark new techniques and algorithms.
