Abstract:


Politically concerned citizens and data journalists want to investigate money flows from government to media, which are documented as open government data on `media transparency´. This dataset can be characterized as a dynamic bipartite network with quantitative flows and a large number of vertices. Currently, there is no adequate visualization approach for data of this structure. We designed a visualization providing coordinated multiple views of aggregated attribute values as well as short tables of top sorted vertices that can be explored in detail by linked selection across multiple views. A derived attribute `trend´ allows selection of flows with increasing or decreasing volume. The design study concludes with directions for future work.
