We have Marian Dörk on the show today to talk about the "Information Flaneur": an approach to data visualization centered on navigating, exploring, browsing and observing data with curiosity to learn about what's there, and to see and be surprised by new thoughts and discoveries. Marian is Research Professor at the University of Applied Sciences Potsdam near Berlin where he works on "exploring novel uses of interactive visualizations to support a wide range of information practices." We talk about many interesting new directions for visualization like visualizing data starting from a few seed points, whether we always need an overview first in visualization, and tips on how to design visualization for "information flaneurs."
