A Beautiful WWW has posted an updated version of their viz of Wikipedia. This version specializes on science and technology articles. The map is generated by first laying out the graph of Wikipedia (nodes are articles, edges are links between articles) and then decorating that substrate with colours (for topics: maths, science and technology) and images. Given the broad swath of science (green) articles, a question that springs to mind is: what is divided by this class - what topics are to the left and right? Could it be that science articles, due to some quality of their authors or topic are more interlinked and consequently take control of the layout algorithm?
