  • gemini2 generating keyframe oriented animated transitions between Statistical Graphics
    arXiv: Human-Computer Interaction, 2021
    Co-Authors: Younghoon Kim, Jeffrey Heer
    Abstract:

    Complex animated transitions may be easier to understand when divided into separate, consecutive stages. However, effective staging requires careful attention to both animation semantics and timing parameters. We present Gemini2, a system for creating staged animations from a sequence of chart keyframes. Given only a start state and an end state, Gemini2 can automatically recommend intermediate keyframes for designers to consider. The Gemini2 recommendation engine leverages Gemini, our prior work, and GraphScape to itemize the given complex change into semantic edit operations and to recombine operations into stages with a guided order for clearly conveying the semantics. To evaluate Gemini2's recommendations, we conducted a human-subject study in which participants ranked recommended animations from both Gemini2 and Gemini. We find that Gemini2's animation recommendation ranking is well aligned with subjects' preferences, and Gemini2 can recommend favorable animations that Gemini cannot support.

  • gemini a grammar and recommender system for animated transitions in Statistical Graphics
    IEEE Transactions on Visualization and Computer Graphics, 2021
    Co-Authors: Younghoon Kim, Jeffrey Heer
    Abstract:

    Animated transitions help viewers follow changes between related visualizations. Specifying effective animations demands significant effort: authors must select the elements and properties to animate, provide transition parameters, and coordinate the timing of stages. To facilitate this process, we present Gemini, a declarative grammar and recommendation system for animated transitions between single-view Statistical Graphics. Gemini specifications define transition “steps” in terms of high-level visual components (marks, axes, legends) and composition rules to synchronize and concatenate steps. With this grammar, Gemini can recommend animation designs to augment and accelerate designers' work. Gemini enumerates staged animation designs for given start and end states, and ranks those designs using a cost function informed by prior perceptual studies. To evaluate Gemini, we conduct both a formative study on Mechanical Turk to assess and tune our ranking function, and a summative study in which 8 experienced visualization developers implement animations in D3 that we then compare to Gemini's suggestions. We find that most designs (9/11) are exactly replicable in Gemini, with many (8/11) achievable via edits to suggestions, and that Gemini suggestions avoid multiple participant errors.

  • the golden age of Statistical Graphics
    arXiv: Methodology, 2009
    Co-Authors: Michael Friendly
    Abstract:

    Statistical Graphics and data visualization have long histories, but their modern forms began only in the early 1800s. Between roughly 1850 and 1900 ($\pm10$), an explosive growth occurred in both the general use of graphic methods and the range of topics to which they were applied. Innovations were prodigious and some of the most exquisite Graphics ever produced appeared, resulting in what may be called the ``Golden Age of Statistical Graphics.'' In this article I trace the origins of this period in terms of the infrastructure required to produce this explosive growth: recognition of the importance of systematic data collection by the state; the rise of Statistical theory and Statistical thinking; enabling developments of technology; and inventions of novel methods to portray Statistical data. To illustrate, I describe some specific contributions that give rise to the appellation ``Golden Age.''

  • milestones in the history of thematic cartography statistica l Graphics and data visualization
    2008
    Co-Authors: Michael Friendly
    Abstract:

    The graphic portrayal of quantitative information has deep roots. These roots reach into histories of thematic cartography, Statistical Graphics, and data visualization, which are intertwined with each other. They also connect with the rise of Statistical thinking up through the 19th century, and developments in technology into the 20th century. From above ground, we can see the current fruit; we must look below to see its pedigree and germination. There certainly have been many new things in the world of visualization; but unless you know its history, everything might seem novel.

  • the early origins and development of the scatterplot
    Journal of The History of The Behavioral Sciences, 2005
    Co-Authors: Michael Friendly, Daniel J Denis
    Abstract:

    Of all the graphic forms used today, the scatterplot is arguably the most versatile, polymorphic, and generally useful invention in the history of Statistical Graphics. Its use by Galton led to the discovery of correlation and regression, and ultimately to much of present multivariate statistics. So, it is perhaps surprising that there is no one widely credited with the invention of this idea. Even more surprising is that there are few contenders for this title, and this question seems not to have been raised before. This article traces some of the developments in the history of this graphical method, the origin of the term scatterplot, the role it has played in the history of science, and some of its modern descendants. We suggest that the origin of this method can be traced to its unique advantage: the possibility to discover regularity in empirical data by smoothing and other graphic annotations to enhance visual perception.

  • Visualizing Categorical Data
    2000
    Co-Authors: Michael Friendly
    Abstract:

    From the Publisher: This book offers many new and more easily accessible graphical methods for representing categorical data using SAS software. Graphical methods for quantitative data are well developed and widely used. However, until now with this comprehensive treatment, few graphical methods existed for categorical data. In this innovative book, Friendly presents many aspects of the relationships among variables, the adequacy of a fitted model, and possibly unusual features of the data that can best be seen and appreciated in an informative graphical display. Filled with programs and datasets, this book focuses on the use, understanding, and interpretation of results. Where necessary, the Statistical theory with a well-written explanation is also provided. Readers will also appreciate the implementation of these methods in the general macros and programs that are described in the book. Supports releases 6.09 and higher of SAS software. Author Biography: Michael Friendly, PhD Michael Friendly, PhD brings a tremendous amount of experience to the conceptualization, research, and writing of this invaluable text. With expertise in statistics, Graphics, and macro writing, Michael has taught graduate-level courses in Multivariate Data Analysis and Computer Methods in Psychology using SAS software for over 25 years. His research includes the development of visulization methods to problems in Cognitive Psychology. Many of the new methods discussed in this book were developed or extended by Michael. He is also the author of SAS System for Statistical Graphics, First Edition.

    Abstract:

    • Display at least three parallel sequences of panels (micromap, label, and Statistical summary) that are linked by position • Sort the study units • Partition the study units into panels to focus attention on a few units at a time • Link the highlighted study units across corresponding panels of the sequences You can use LM plots to visualize complex data in many areas. 1–3 This column extends the existing work by introducing Web-based interactive LM plots, a Statistical data visualization system that integrates geographical data manipulation, visualization, interactive Statistical Graphics, and Webbased Java technologies. The system effectively presents the complex and large-volume sample data of national cancer statistics of the United States. Structure and features Displaying LM plots on the Internet introduces a new and effective way to visualize Statistical summaries. Through a Web browser, a user can easily access and view the Statistical data in LM plots—globally. Effective Web-based LM plots include many interactions that require retrieving new data from the Web server and displaying it in different layouts to help users. The Java programming environment provides mechanisms that let users interactively control a Web browser’s display content, so we used Java as the programming tool in our implementations. Although spatial resolution is lost in the transition from the printed page to a computer monitor, the interactive viewing options allowed better visualization through drill-down views, multiple levels of detail, sorting, magnified micromaps, miniature overall Statistical summaries, confidence interval switching, and other interactive visualization methods. These methods are not new individually, but their integration with LM plots provides a new approach to communicating spatially indexed Statistical summaries over the Internet. We used cancer statistics from th

  • 26 Statistical Graphics and visualization
    Computational Statistics, 1993
    Co-Authors: Edward J Wegman, Daniel B Carr
    Abstract:

    Publisher Summary This chapter focuses on the use of Graphics and visualization methods for Statistical analysis. The traditional use of Graphics in statistics had been principally relegated to simple two-dimensional Graphics, such as scatterplots and histograms. However, modern computer Graphics methods introduce a host of new techniques that literally allow an explosion of new methods for a much more geometric understanding of Statistical and scientific data. Computer Graphics allows an easy leap to visualizing three-dimensional data and to using animation, lighting, rendering, transparency, and a host of other techniques. The chapter covers some of the basic elements of computer-based Graphics and gives an overview of some of the resulting Statistical Graphics and visualization methods. Geographic information system (GIS) is one of the spin-off technologies from the revolution in computers and computer Graphics and is closely linked to spatial data representation via Graphics. Geometry clearly plays a central role in computer and Statistical Graphics. If geometry plays a pivotal role in Graphics and visualization, an equally pivotal role is played by the area of the vision theory.
