English: From the paper: "(a), Time series of traffic. The grey lines represent the daily traffic to articles that are linked from/to the article “2012 Summer Olympics,” according to a recent snapshot of Wikipedia (see Methods). For visualization purposes, only a random sample of 100 neighbors is shown. The focal page is represented by the black solid line; red and gold lines represent the average and median traffic, respectively. The vertical black segments represent the times when new linked articles are created (see Methods). (b), Network of neighbors of “2012 Summer Olympics.” White nodes represent the neighbor articles predating 2012; colored nodes correspond to neighbors created in 2012. The size of the nodes is proportional to their yearly traffic volume; their position was computed using the ARF layout32. (c and d), Same visualizations as (a) and (b) for the entry about Hurricane Sandy and its neighbors. New articles tend to be peripheral to these networks."
