Temporal evolution of "Le Tour de France 2014" cyclists ranking after each stage. In contrast to standard snapshot ranking tables used to represent this ranking, our visualization clearly shows the temporal evolution of each cyclist’s ranking and global trends for each stage.
The image shows the evolution of 198 cyclists' rankings after each of the 21 stages of the Tour de France. The magnitude landmarks (thin gray lines) represent 1 minute gaps between cyclists. Colors encode cyclists’ nationality, and stage miniatures provide context at the top. The chart clearly shows that many changes occurred in the rankings during the second stage of the race, which means this stage was key. After that, rankings remained stable for three stages, before changing dramatically once again. Tour de France enthusiasts will also see that 'flat terrain stages' generally do not impact rankings or gap magnitudes, whereas 'mountain stages' strongly impact both.
The expert eye will see that Valverde lost his second position three stages before the end of the race, and that Porte constantly decreased in ranking during high mountain stages, while he was ranked second.

Evolution of the top 100 universities' rankings over 10 years, according to the ARWU Shanghai University Ranking, using a Gap Chart. Colors encode world regions (North America in purple, Europe in orange, Asia in green, and unclassified in dark gray). The most immediate observation is that the entry ranked first (Harvard University) is far above all others. Below that, several universities struggle for the top-5 ranks, while competition is fierce at the bottom of the ranking. Nearly half the top-100 universities are North American; only five European and two Asian universities are among the first third. It is also interesting to point out that rankings varied a lot between 2003 and 2005. This was simply due to modifications of the ranking formula.
