| Summary: | Glyph-based visualization is one of the main techniques for visualizing complex multivariate data. With small
glyphs, data variables are typically encoded with relatively
low visual and perceptual precision. Glyph designers have to
contemplate the trade-offs in allocating visual channels when
there is a large number of data variables. While there are many
successful glyph designs in the literature, there is not yet a
systematic method for assisting visualization designers to evaluate
different design options that feature different types of tradeoffs. In this paper, we present an evaluation scheme based on
the multi-criteria decision analysis (MCDA) methodology. The
scheme provides designers with a structured way to consider their
glyph designs from a range of perspectives, while rendering a
semi-quantitative template for evaluating different design options.
In addition, this work provides guideposts for future empirical
research to obtain more quantitative measurements that can be
used in MCDA-aided glyph design processes.
