For the Bern Open Data Camp on April 27, 2012 we were generously sponsored by Netcetera to print a custom t-shirt for every participant. We had to come up with a design quickly based on brand new Opendata.ch logos designed by Thierry Blancpain. What better way to express the theme of our event than with Open Data?

Desiring to make a design that suggests a “splashing out” of data, we took the national statistics of cantonal populations, distributed them based on the geographical location of each canton, and plotted a circle with a representative area. Of course the possibilities are endless for more complicated visualizations, and we hope that more creative designs will be used on future Open Data wear.
