cf. city flows by Till Nagel and Christopher Pietsch
cf. city flows is a comparative visualization of urban bike mobility designed to help citizens casually analyze bike-sharing systems in the context of a public exhibition space. Three high-resolution screens show the space of flows of New York, Berlin, and London. By showing the flow of multiple cities side by side, we can compare their extent and dynamics. With our visualizations we want to understand the pulse of urban mobility and create portraits of a city defined by its transient dynamics.
