• Augmenting Visualization with Natural Language Translation of Interaction: A Usability Study 

  Nafari, Maryam; Weaver, Chris (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  As visualization tools get more complicated, users often find it increasingly difficult to learn interaction sequences, recall past queries, and interpret visual states.We examine a query-to-question (Q2Q) supporting system ...

• Selecting Semantically-Resonant Colors for Data Visualization 

  Lin, Sharon; Fortuna, Julie; Kulkarni, Chinmay; Stone, Maureen; Heer, Jeffrey (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  We introduce an algorithm for automatic selection of semantically-resonant colors to represent data (e.g., using blue for data about ''oceans'', or pink for ''love''). Given a set of categorical values and a target color ...

• Rule-based Visual Mappings - with a Case Study on Poetry Visualization 

  Abdul-Rahman, Alfie; Lein, Julie; Coles, Katharine; Maguire, Eamonn; Meyer, Miriah; Wynne, Martin; Johnson, Chris R.; Trefethen, Anne; Chen, Min (The Eurographics Association and Blackwell Publishing Ltd., 2013)

• Fingerprint Matrices: Uncovering the Dynamics of Social Networks in Prose Literature 

  Oelke, Daniela; Kokkinakis, Dimitrios; Keim, Daniel A. (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  In prose literature often complex dynamics of interpersonal relationships can be observed between the different characters. Traditionally, node-link diagrams are used to depict the social network of a novel. However, static ...

• A Primal/ Dual Representation for Discrete Morse Complexes on Tetrahedral Meshes 

  Weiss, Kenneth; Iuricich, Federico; Fellegara, Riccardo; Floriani, Leila De (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  We consider the problem of computing discrete Morse and Morse-Smale complexes on an unstructured tetrahedral mesh discretizing the domain of a 3D scalar field. We use a duality argument to define the cells of the descending ...

• Towards Multifield Scalar Topology Based on Pareto Optimality 

  Huettenberger, Lars; Heine, Christian; Carr, Hamish; Scheuermann, Gerik; Garth, Christoph (The Eurographics Association and Blackwell Publishing Ltd., 2013)
