Two Novel Techniques for Interactive Navigation of Graph Layouts
Christian Tominski, James M. Abello, Heidrun Schumann · 2009
Navigation of the view space is an essential task during visual exploration of graphs. A fairly standard approach not only in graph visualization is to let users grab a view and drag it as necessary. Though being a very natural and intuitive interaction, it implies higher physical costs in terms of mouse milage [Harrower and Benjamin 2005]. To alleviate these costs, we propose two alternative navigation methods: pan-wheel navigation with radar view for the view space and edge-based travelling as a dedicated data space navigation method.
