Poster at IEEE VIS 2015

July 2015 IEEE, conference, poster

Our poster Where Can I Go From Here? Drawing Contextual Navigation Maps of the London Underground was presented in IEEE VIS2015 held in Chicago, IL. You can have a look at the accepted papers, news and updates from the symposium at VIS2015.

Abstract - Network administrators often wish to ascertain where network attackers are located; therefore it would be useful to display the network map from the context of either the attacker’s potential location or the attacked host. As part of a bigger project we are investigating how to best visualize contextual network data. We use a dataset of station adjacencies with journey times as edge weights, to explore which visualization design is most suitable, and also ascertain the best network shortest-path metric. This short paper presents our initial findings, and a visualization for Contextual Navigation using circular, centered-phylogram projections of the network. Our visualizations are interactive allowing users to explore different scenarios and observe relative distances in the data.

Contextual Navigation (CN) creates topological projections centered on a given point. Routes to the remainder of the network radiate from this point. Especially useful for creating maps to answer ‘Where can I go from here?’.
