Description

On March 13, 2016, three of Germany's 16 federal states got to vote their parliaments. Right the day after, we visualized data from Infratest Dimap, an opinion research institute that conducts post-election surveys: how many of them voted for the same party they voted the last time? How many decided to vote for a different one? We visualized these flows of voters from every party in 2011 to all parties in 2016. Also, how many non-voters decided to vote, how many first time voters there were for each party, how many of the 2011 voters died, and so on. Full credits: Julian Stahnke, Paul Blickle, Sascha Venohr and Ludwig Greven

What makes this project innovative? What was its impact?

We enriched the visualization type, which is basically a Sankey Diagram and has been used for voter shifts before, with a new and very helpful feature for the reader: it is possible to clik/tap a party or group and zoom into the diagram. When choosing a party/group of 2016, it's easy to see from what other parties the "come from". The other way around, by clicking on a 2011 group/party, one can see which parts of the voters "went" to a different party, stayed, chose not to vote, moved away, died etc.
