“This video depicts European birth to death network dynamics 0 to 2012 CE according to “deceased persons” in Freebase.com.”
“In the current video, the dynamically applied color scheme indicates birth sources (blue) and death attractors (red). Individuals in the videos appear as particles gravitating towards their death locations, indicating collective directions of flow. The video is rendered with one frame per year at 30 frames per second.”
