The voter transition analysis allows the user to see how the votes transitioned from one party to another after the elections. The idea is a simple one: if a party gains most votes in those municipalities in which another party had the most votes at the election before, it is interpreted as a vote transition between those parties.
This method is very popular in countrys like Austria and Germany but doesn’t really work in 2-Party systems like the US.
Below you can see some examples of interactive voter transition analysis:
