Visualizing Citation Patterns

I found a nice example of how to visualize information flow in science. The Eigenfactor Project (data analysis) and Moritz Stefaner (visualization) cooperated on this interactive visualizations which is based on the Eigenfactor™ Metrics and hierarchical clustering in order to explore emerging patterns in citation networks. It shows citation patterns over time, a clustering and maps based approximately 60,000,000 citations from more than 7000 journals over the past decade. Interestingly, a recent blog at BMJ Group blogs by Richard Smith “The beginning of the end for impact factors and journals” discussed the end of impact factors as a measure of research quality and their substitution by article-level metrics (see Next Generation Science)
