The 2017 Gordon Research Conference on Visualization in Science and Education will continue a tradition of bringing together a diverse community of practitioners and researchers engaged in the production, study, and application of visualizations to advance and promote scientific understanding. The theme for the 2017 conference is "Scientific Visualization for Decision-Making". This interdisciplinary meeting will explore the various ways that data are visualized and leveraged to help diverse stakeholders make informed decisions based on scientific evidence. Speakers will discuss the cognitive underpinnings of human decision-making and how it is affected by the availability of visualizations. Presentations will include cutting-edge research on how visualizations support both the day-to-day decisions made by investigators and case studies of visualizations proven critical for scientific discovery. Novel research will also be presented that demonstrates how the design of a visualization influences decisions made by policymakers and the general public.
