This document summarizes a workshop on data visualization best practices for graduate student group projects at the Bren School of Environmental Science and Management at UC Santa Barbara. The workshop covered topics such as choosing visualizations based on audience and purpose, using visuals to tell stories with data, and focusing visuals to draw attention to key points. Examples were provided of effective and ineffective visualizations from past student projects. Students practiced improving sample diagrams based on the principles discussed.

- 40. Notes from discussion: * avoid noise: colors that don’t make sense, shapes that aren’t significant, arrows that don’t serve a purpose. This information can be mis-interpreted. * if linear relationship, show it, don’t complicate it with unnecessary info. * is it necessary for each box to be separate? Combine related information.
