We are currently running an online study on the effect of aesthetics in data visualization. The purpose of the study is to measure what non-trivial and unexpected insights are found from interacting with a specific data representation. The study is part of a collaborative research project between K.U. Leuven, Vienna University of Technology, and the University of Sydney. If you have about 10-20 minutes of uninterrupted time please help us by completing the study at: http://www.aesthetic-impact.com/ The main task that will be expected from you, is to interact with a visualization, and to describe what you have learned from it. The study is anonymous and the collected data will only be used for research purposes. Should you have any questions about the study, please don't hesitate to contact us at study@aesthetic-impact.com. Please help us by distributing this message, including people outside the infovis community. Thank you in advance.
