3 Lengler, Ralph Eppler, Martin of the Conference on Graphics and Visualization in Engineering (GVE 2007) Clearwater, Florida, USA 6 P. In this paper, we describe the effort of defining and compiling existing visualization methods in order to develop a systematic overview based on the logic, look, and use of the periodic table of elements. We first describe the current fragmented state of the visualization field. Then we outline the rules and criteria we applied in conducting our research in order to present a revised periodic table of 100 visualization methods with a proposition how to use it. http://www.visual-literacy.org/periodic\_table/periodic\_table.pdf
