    This paper discusses the works of Artist Frank Bonilla, a visual artist. He uses a photo editing program called ACDSee Pro in all of his digital artwork. His hundreds of colorful digital images were created in an ad lib, free style, random, and unplanned process that is adventurous and exploratory. View full abstract»

    As news migrates to mobile phones, media companies are turning to data visualization to wet readers' appetites for stories they can read at length on their home or work computers. Journalists are trained to write stories, not in statistics or coding, however. The big news organizations have the funds to hire computer graphics experts, but local news organizations need help.

    Personal visualizations have the great potential to provide the benefits of visualizations to everyone in their everyday lives. Their diverse goals combined with the personal data they contain and the contexts in which they are being used, however, make their evaluation particularly challenging and call for a wider perspective on empirical approaches. We need to devise new methods and adapt existi... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (3182 KB)

    An evaluation structure is a hierarchical structure of human cognition extracted from interviews based on the evaluation grid method. An evaluation structure can be defined as a directed acyclic graph (DAG). The authors propose a layer-assignment method that is part of the Sugiyama framework, a popular method for drawing DAGs, to satisfy the requirements for drawing evaluation structures. Their ev...

  • Glyph Visualization: A Fail-Safe Design Scheme Based on Quasi-Hamming Distances

    Publication Year: 2017, Page(s):31 - 41
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (2812 KB)

    In many spatial and temporal visualization applications, glyphs provide an effective means for encoding multivariate data. However, because glyphs are typically small, they are vulnerable to various perceptual errors. This article introduces the concept of a quasi-Hamming distance in the context of glyph design and examines the feasibility of estimating the quasi-Hamming distance between a pair of...

    Visual clutter is a common challenge when visualizing large rank time series data. WikiTopReader, a reader of Wikipedia page rank, lets users explore connections among top-viewed pages by connecting page-rank behaviors with page-link relations. Such a combination enhances the unweighted Wikipedia page-link network and focuses attention on the page of interest. A set of user evaluations shows that ... View full abstract»

    The Web-based visualization VisAdapt tool was developed to help laypeople in the Nordic countries assess how anticipated climate change will impact their homes. The tool guides users through a three-step visual process that helps them explore risks and identify adaptive actions specifically modified to their location and house type. This article walks through the tool's multistep, user-centered de... View full abstract»

    As wearable devices gain acceptance, we need to ask, What will user interfaces look like in a post-smartphone world? Will these future interfaces support sophisticated interactions in a mobile context? The authors draw from visual analytics concepts to address the growing need for individuals to manage information on personal devices. Spatial analytic interfaces (SAIs) can leverage the benefits of... View full abstract»

    Years of research have been devoted to computer-generated 2D marbling, whereas 3D marbling has yet to be explored. The proposed mathematical marbling of 3D solids supports a compact random-access vector representation, creating solid marbling textures by composing closed-form 3D pattern tool functions. The resulting representation is feature-preserving and resolution-independent, and it consumes v... View full abstract»

    Recent advances in web development, including the introduction of HTML5, have opened a door for visualization researchers and developers to quickly access larger audiences worldwide. Open source libraries for the creation of interactive visualizations are becoming more specialized but also modular, which makes them easy to incorporate in domain-specific applications. In this context, the authors d... View full abstract»
