Staged Analysis
No full textIn this paper we examine the concept of staged analysis through a case study on visualizing urban mobility exhibited in a public gallery space. Recently, many cities introduced bike-sharing in order to promote cycling among locals and visitors. We explore how citizens can be guided from evocative impressions of bicycling flows to comparative analysis of three bike-sharing systems. The main aim for visualizations in exhibition contexts is to encourage a shift from temporary interest to deeper insight into a complex phenomenon. To pursue this ambition we introduce cf. city flows, a comparative visualization environment of urban bike mobility designed to help citizens casually analyze three bike-sharing systems in the context of a public exhibition space. Multiple large screens show the space of flows in bike-sharing for three selected world cities: Berlin, London, and New York. Bike journeys are represented in three geospatial visualizations designed to be progressively more analytical, from animated trails to small-multiple glyphs. In this paper, we describe our design concept and process, the exhibition setup, and discuss some of the insights visitors gained while interacting with the visualizations
Visualizing the spatiality in fictional narratives
No full textThis work is part of ongoing research on the visualization of spatial relationships in fictional works. Our aim is to arrive at aesthetic representations of fictional narratives set in actual places such as cities. Novel City Maps offers two map views, one inspired by transit maps and the other by conventional street maps. The former uses the aesthetic of abstract transit maps to reveal the co-occurrence structures between important places in a story. The street map view is designed as a spatial fingerprint of a novel by highlighting the places occurring often in the story
