    Designing Effective Network Visualization Representations of Disinformation Operations - Improving DisInfoVis
    (The Eurographics Association, 2020) Pavliuc, Alexandra Melania; Dykes, Jason; Byška, Jan and Jänicke, Stefan
    Practitioners working to understand, combat, and inform the public about disinformation operations need tools to analyse these complex social phenomena, and communicate their findings to stakeholders. Temporal network visualization presents a means of analysing and communicating this dynamic socio-technical phenomenon, but comes with visualization design challenges that can be addressed through judicious iterative design and empirical evaluation. We present a path towards tailoring temporal network visualizations for DisInfoVis through qualitative evaluation, and outline a design for representing disinformation operations in social media networks informed by this process and used in public communication.

    Towards a WHAT-WHY-HOW Taxonomy of Trajectories in Visualization Research
    (The Eurographics Association, 2019) Allain, Kevin; Turkay, Cagatay; dykes, jason; Madeiras Pereira, João and Raidou, Renata Georgia
    Effective analysis of movement often requires a comprehensive approach where computational and visual methods are combined to address a wide variety of tasks involving movers with diverse characteristics. In order to help the process of designing effective methods for a wide range of movement analysis cases, we develop a provisional taxonomy that links what Brehmer et al. [BM13] term statements of WHY-WHAT-HOW with tasks, types of movers, context and methods used to compute or visualize data. Within this document we present the origin of this taxonomy, the process we followed to populate it, discuss the novel categories within it, and finally use it to explore relationships between elements of trajectory analysis. Our main contribution is to provide a new means of connecting elements of WHY-WHAT-HOW when analysing trajectories.
