From Moritz Stefaner, the same person who created the elegant “elastic” Noble Price lists, comes the brand-new Eigenfactor: Visualizing Information Flow in Science []. The project contains 4 beautiful interactive data visualizations that explore the emerging patterns in scientific citation networks.

Citation Patterns” provides an overview of the whole citation network in a circular graph. The colors represent the 4 main groups of journals, which are further subdivided into fields in the outer ring. Line size and opacity represents connection strength

Change over Time” is a combination of a Sankey Diagram (see some other examples here and here) and a stacked bar graph. It shows the changes in the “Eigenfactor Score” and clustering over time. Journals are grouped vertically according to their cluster structure. Bars belonging to the same journal are connected.

The “Clustering” graph displays a hierarchical clustering of journals in the form of a treemap …with a twist: rectangles can be clicked to reveal directional black arrow that indicate the outgoing versus incoming citation flow. The size of a journal marker corresponds to its “Eigenfactor Score”.

Finally, the “Map” shows an interactive network graph clustering those which frequently cite each other, closer together. The node sizes represent the relative amount of citation flow.


In a world where fortunes are sought through data-mining vast information repositories, the computer is our indispensable but far from infallible assistant. Personas demonstrates the computer’s uncanny insights and its inadvertent errors, such as the mischaracterizations caused by the inability to separate data from multiple owners of the same name. It is meant for the viewer to reflect on our current and future world, where digital histories are as important if not more important than oral histories, and computational methods of condensing our digital traces are opaque and socially ignorant.


Virtual Gravity [] is an interactive data sculpture that makes a bridge between the digital and the analog world. Individual keywords can be selected and transported from a computer screen to an analog scale. The importance and popularity of these terms, determined by Google Insights for Search, are then represented as virtual weights, which can be physically compared on the scale.

The interaction metaphor used is to compare the “virtual weight” of information of 2 virtual objects, which takes place over an intuitively useable analog instrument: a scale. The interaction and representation of information occurs exclusively by the physical behaviour of the scale. Output of numerical values is totally renounced. In this way, the focus lies on the purely emotional information processing.
