Citation Map: Visualizing the Spread of Scientific Ideas Through Space and Time

Team members: Yingjie Hu, Grant McKenzie, and Song Gao
We designed a Citation Map for the Robert Raskin Mashup Mapping competition. This web mapping application is a novel approach to visualize research topics, authors, publications, as well as their citation relations on a world map. By displaying the geographic distribution of research paper citations, this dynamic web map shows how a scientific idea spreads through space and time (i.e. How a scientific publication is accepted and cited by researchers in different countries over the years). This Citation Map also shows the researchers who has cited a particular paper most frequently, and where are these researchers.
