    How Effective are Uni- and Multivariate Typographic Encodings? Studying the Usage of FontWeight, Oblique Angle, and Spacing
    (The Eurographics Association, 2022) Bäuerle, Andreas; Brath, Richard; El-Assady, Mennatallah; Agus, Marco; Aigner, Wolfgang; Hoellt, Thomas
    Text is one of the most commonly used ways to transmit information. It is widely used in various visualizations and determines our understanding of the presented content. The information density of text can be enhanced by visualizing data in typographic attributes, such as font weight, letter spacing, or oblique angle. To increase information density the furthest, without the visualization losing performance or effectiveness, the perceivable granularity of the typographic attributes needs to be known. In an empirical experiment, the number of distinguishable levels in typographic attributes and the effects of changing the associated font size or facilitating multivariate encoding are assessed. Findings facilitate designing information-dense typographic visualizations without decreasing their performance or effectiveness.

    Many Types of Design Needed for Effective Visualizations
    (The Eurographics Association, 2023) Brath, Richard; Gillmann, Christina; Krone, Michael; Reina, Guido; Wischgoll, Thomas
    For effective visualizations, there are many types of design to consider. Visualization design focuses on core theory of tasks, data and visual encodings. Workflow design, user interface design and graphic design all contribute to a successful visualizations. All design aspects range from initial design exploration to iterative design refinement. Guidelines can help, but have limitations. Examples illustrate visualization issues arising from missing domain knowledge, facilitating alternative designs, refining labeling, layouts to aid workflow, frankenvis, 3D timeseries, and ineffective design collaboration.
