Over the last few years Information Visualization has gone beyond its academic and expert only roots. Visualizations have become a tool for mass communication. Visualizations that go beyond barcharts and scatterplots have for example made their way into digital as well as printed news products, they appear on tv or in reports like the IPCC report on climate change. As those techniques move into the public realm of information consumption, it becomes even more important than in the past, that we also look at how users are using, reading and understanding those visualizations.
Through our research we are not only trying to optimize the way we produce visualizations and make them more legible and easier to understand for experts and laymen alike, but we are also trying to push the boundaries of visual literacy.
