Quartz ran this interesting data-visualization of cultural migration.

Dr. Maximilian Schich, associate professor for art and technology at the University of Texas at Dallas, and his team took data on more than 100,000 notable figures—people important enough to have their births and deaths catalogued—from Google’s information tank, Freebase, and digitally plotted it on a map visualizing changes over hundreds of years. Blue dots signify births, red dots mark deaths. The more dots in a given location, the bigger the visualization.
