Erasmus is an European Union student exchange program that allows more than 75.000 European students to travel abroad and study in a country different from their home. The network consists of over 2.900 universities, which are interconnected by over 90.000 partnerships.

Christian Gross and Sebastian Sadowski have implemented an interactive visualization of the network [], revealing all the academic institutes that participate in the program, in addition to the student flows of the ‘top 100’ receiving and sending universities.

The second series of visualizations reveals the reasons why students go abroad, on a per country level. This information is contrasted with the average temperature, Consumer Price Index (CPI) and distance to the home country.
