Aaron Koblin, famous for his work with Flight Patterns and other interactive visualizations, has a great presentation at TED where he discusses the many ways you can introduce the human element into visualizations.

Artist Aaron Koblin takes vast amounts of data — and at times vast numbers of people — and weaves them into stunning visualizations. From elegant lines tracing airline flights to landscapes of cell phone data, from a Johnny Cash video assembled from crowd-sourced drawings to the “Wilderness Downtown” video that customizes for the user, his works brilliantly explore how modern technology can make us more human.
