Network analysis Eurovision Song Contest 1975-2015

We took all the scores from the finales. We averaged the points each country gave to another country. Then we filtered out the connections with only a single vote. And we fed the data into Gephi.

Using the "forced atlas" algorithm already a certain distribution became clear. And finally we ran the build in modularity algorithm which colored the clusters.
It only adds to the many discussions about voting patterns going on this week.

We've put a interactive version online using the GEXF-viewer. The modularity coloring is not supported there.
Using the interactive version you can check the average scoring from one country to and from another. Just click on a country node.

Some interesting statistics

Three combinations averaged 12 points over several years:

Cyprus gave Greece an average 11.2 points over 26 years of voting. And vice versa 10.2 points average over 20 years.

Turkey gave Cyprus an averag of just 0.04 points over 24 years of voting.

Moldova gave 11.3 points averaged over 10 years to Romania and vice versa it received 11.7 from Romania over 8 years.

Other analysis on same subject from last year.

Update 12-05-2016: we've created a matrix for easy lookup on the figures.
