Visualization and the use of graphics can help at every stage of an analysis, from the planning and design of an experiment, the very first data explorations, through to the communication of conclusions and recommendations. Visualization is more than "plotting data"; it can lead to a deeper understanding and inform next steps. The role of the STRATOS visualization panel is to promote the use of good graphical principles for effective visual communication, providing guidance and recommendations covering all aspects from the design, implementation and review of statistical graphics.
