http://www.visualcomplexity.com/vc/ is an archive for data visualization. 

VisualComplexity.com intends to be a unified resource space for anyone interested in the visualization of complex networks. The project's main goal is to leverage a critical understanding of different visualization methods, across a series of disciplines, as diverse as Biology, Social Networks or the World Wide Web. I truly hope this space can inspire, motivate and enlighten any person doing research on this field.

Search on "web trend map" to see a visualization of "... all the big players [in the web world], ordered by category, proximity, success, popularity and perspective; using the Tokyo Metro map as an underlying reference."
