A must-see visual presentation showing how
immigration to the United States has changed in volume and source over the
last two centuries has been created by Max Galka, who describes himself as
"fascinated by data" and maintains a website, Metrocosm.com, that presents
visualizations of data. He writes that he teaches:
... data wrangling + data visualization at the University of Pennsylvania. And
I write about data visualization as a Guardian and Huffington Post contributor. Previously,
I worked for 10 years as a trader at Deutsche Bank and Credit Suisse[.]

is a still screen grab of one moment of his two centuries.
