Apologies for any duplication Effective Data Visualization Practices | CORS Workshop | Monday, June 25, 2012, Anaheim, CA Anaheim Convention Center, Room 203A by Ray Lyons, MLIS, MPA The workshop will provide an overview of best practices in the graphical presentation of quantitative information, emphasizing the need for clarity, fairness, and efficiency. The purpose of data visualization is to display data impartially in order to uncover the ‘stories’ data have to tell. Attendees will learn to adopt practices that enhance effective portrayal of these stories and to avoid those that interfere. Guidelines for choosing chart styles, labeling and captioning, determining axis scaling, use of color, improving readability, and highlighting key data patterns will be presented. Examples of poor practices lurking in popular graphical software features will be included.
