Inspired by Paul Butler’s Facebook visualization, Olivier Beauchesne has constructed something similar based on a database of scientific collaboration: “From this data, I extracted and aggregated scientific collaboration between cities all over the world. For example, if a UCLA researcher published a paper with a colleague at the University of Tokyo, this would create an instance of collaboration between Los Angeles and Tokyo.” The result is this map of scientific collaboration between researchers.
