TimeRadarTrees is a novel representation method which shows the information hierarchy as a traditional node-link diagram but in a radial style. Each graph is represented as a slice on the inner circle and corresponding slices on the smaller outer circles, in what the authors call thumbnails. The inner circle shows the incoming edges, while thumbnails represent the outgoing edges.The first images highlights the world's fuel exports with expanded hierarchy parts. The second image shows a time period of the soccer match between Germany and the Netherlands in the World Cup of 1990 in Italy.
