The CEU Data Stories is an exhibition of research visualizations on social and behavioural topics. We are very pleased to announce that the exhibition also featured the joint work by Erik Braun, András Gyimesi and Eszter Kovács, entitled "Temporal Network of all UEFA Champion League matches".
The visualization (click on the picture) displays a multilayer temporal network of the UEFA Champions League (CL), where the nodes are the teams and the edges represent the number of CL matches between them. The three temporal layers show three distinct eras: (1) the 90s when initially only champions could qualify, (2) the 2000s when the 32-team group stage format was introduced, and (3) the 2010s when the prize pool started to drastically increase and the Financial Fair Play regulations were introduced. The aim of this project is to capture the evolution of the core-periphery structure. By visualizing the temporal dynamics we can track each team’s route to global fame or fade into obscurity.
