The effect of the organization and selection of visual design elements in digital visualization design will directly affect the efficient transmission of data information. The key points of visual design elements in data visualization which are embodied in three aspects: element, style and order were analyzed, and the design elements included in each aspect were refined and classified, how these elements convey information in data visualization was described, then the application principles and methods of these morphological elements were analyzed one by one. The results of experimental part of this paper from the overall analysis of the previous data to the final presentation in data visualization design are based on the theoretical research of the morphological design. In the visual design of data, the effective grasp of the visualization design elements can strengthen the communication of information and the understanding of the audience.

The aim of this research is to develop automated computational methods that visualise a particular social dimension of teamwork, the mutual expectations and shared knowledge that form the basis for effective collaborative work, to better facilitate its accurate analysis and interpretation. This teamwork dimension is operationalised as conceptual coherence, which is imputed from the semantic coherence of team communication. This paper presents three different information visualisation techniques for representing the social dynamics of design team collaboration based on the content of their communication. This collection of data representations was developed using a custom-made software toolkit that merges computational linguistic and information visualisation algorithms. Based on this research, several teamwork visualisation guidelines have been derived in order to transform the communications of design teams into useful devices for quantifying and representing social accounting metrics concerning the level and quality of their collaborative interactions over time.

When designing a representation, the designer implicitly formulates a sequence of visual tasks required to understand and use the representation effectively. This paper aims at making the sequence of visual tasks explicit in order to help designers elicit their design choices. In particular, we present a set of concepts to systematically analyse what a user must theoretically do to decipher representations. The analysis consists of a decomposition of the activity of scanning into elementary visualization operations. We show how the analysis applies to various existing representations, and how expected benefits can be expressed in terms of elementary operations. The set of elementary operations form the basis of a shared language for representation designers. The decomposition highlights the challenges encountered by a user when deciphering a representation and helps designers to exhibit possible flaws in their design, justify their choices, and compare designs. We also show that interaction with a representation can be considered as facilitation to perform the elementary operations.

While information visualization frameworks and heuristics have traditionally been reluctant to include acquired codes of meaning, designers are making use of them in a wide variety of ways. Acquired codes leverage a user's experience to understand the meaning of a visualization. They range from figurative visualizations which rely on the reader's recognition of shapes, to conventional arrangements of graphic elements which represent particular subjects. In this study, we used content analysis to codify acquired meaning in visualization. We applied the content analysis to a set of infographics and data visualizations which are exemplars of innovative and effective design. 88% of the infographics and 71% of data visualizations in the sample contain at least one use of figurative visualization. Conventions on the arrangement of graphics are also widespread in the sample. In particular, a comparison of representations of time and other quantitative data showed that conventions can be specific to a subject. These results suggest that there is a need for information visualization research to expand its scope beyond perceptual channels, to include social and culturally constructed meaning. Our paper demonstrates a viable method for identifying figurative techniques and graphic conventions and integrating them into heuristics for visualization design.

Visualizations often encode numeric data using sequential and diverging color ramps. Effective ramps use colors that are sufficiently discriminable, align well with the data, and are aesthetically pleasing. Designers rely on years of experience to create high-quality color ramps. However, it is challenging for novice visualization developers that lack this experience to craft effective ramps as most guidelines for constructing ramps are loosely defined qualitative heuristics that are often difficult to apply. Our goal is to enable visualization developers to readily create effective color encodings using a single seed color. We do this using an algorithmic approach that models designer practices by analyzing patterns in the structure of designer-crafted color ramps. We construct these models from a corpus of 222 expert-designed color ramps, and use the results to automatically generate ramps that mimic designer practices. We evaluate our approach through an empirical study comparing the outputs of our approach with designer-crafted color ramps. Our models produce ramps that support accurate and aesthetically pleasing visualizations at least as well as designer ramps and that outperform conventional mathematical approaches.

Information visualizations are often evaluated as a tool in terms of their ability to support performance of a specific task. This article argues that value can be gained by instead evaluating visualizations from a conununicative perspective. Specifically, it explores how text visualization can influence the impacts that framing has on the perception of political issues. Using data from a controlled laboratory study, the results presented here demonstrate that exposure to a text visualization can mitigate framing effects. Furthermore, it also shows a transfer effect, where participants who saw the visualization remained uninfluenced by framing in subsequent texts, even when the visualization was absent. These results carry implications for the methods used to evaluate information visualization systems, for understanding the cognitive and interpretive mechanisms by which framing effects occur, and for exploring the design space of interactive text visualization.

The construction of an artifact to visually represent information is usually required by Information Visualization research projects. The end product of design science research is also an artifact and therefore it can be argued that design science research is an appropriate research paradigm for conducting Information Visualization research. Design science research requires that, during the Rigor Cycle, the design of the artifacts should be based on a scientific knowledge base. This article provides a knowledge base in the form of design guidelines that can guide the design of the view for an Information Visualization solution. The design principles and guidelines presented in this article are identified by means of a literature review.

Abstract Design science is a recognized information systems research paradigm, which is fundamentally centered on problem solving through technology design. The design process involves reflexive thinking and exploration and is usually supported by a variety of visual artifacts, which facilitate structuring, combining, and communicating design knowledge. Visual artifacts are among possible main contributions of a design science endeavor. In this study, we analyze the nature and purpose of such visual artifacts. We adopt semiotics and a theory of visualization of thought, in combination with a literature review, to elaborate a framework of design science visual artifacts. We consider three domains of analysis: intentionality, form-and-function, and visual scheme. We demonstrate the applicability of the framework using two examples. Finally, we define a set of properties that researchers should consider when creating and using visual artifacts in design science: transparency of the relationship between representation and object, self-sufficiency of the visual artifact, and consistency of knowledge communication. The proposed framework helps researchers understand what properties should be focused on when developing their visual artifacts.

Although there are many visualization authoring tools, often the design process is confirmatory in that the user either selects and refines pre-built visualization templates or manually constructs the visualization following the standard visual mapping pipelines. During this process, an amount of time is spent on the interactive specification of visual forms or visual encoding configurations. In this paper, we present a novel visualization design scheme that provides operational guidance for progressive refinements when designing a visualization. The key idea is an evolutional operation model that models the design flowchart as a composition of a sequence of operations based on the current design and recommends available evolutions in the design space. One distinct advantage of our approach is that it facilitates discovering design subtasks relevant to the visualizations and enables the composition of a visualization based on the evolutional operations. As a demonstration of the concept, we implement a prototype and test its efficiency on a set of challenging design examples. Case studies verify that the proposed scheme effectively enhances the creativity of designs and releases the user from having to interpret their data and design intention with toolkit-specific abstractions.

The goal of this to paper is to present the Strategy Map: a visualisation tool for planning and activating design strategy. This paper highlights not only the beneficial practical aspect of this tool but also the epistemological background that will allow flexible, adaptable, and holistic thinking and practices when working with it. The Strategy Map (SM) is the result of a Master's Research that aimed to develop integral design practices. As a method, SM was effective in planning design strategy, and at the same time as a visualising tool. Thus, this paper focuses on developing the theoretical background of the SM, not present in the master's dissertation, and construct a step-by-step process on how to implement it for strategic planning. This is not a case study paper; it is an article that will describe in depth the epistemological foundations of a method-tool designed to develop integral strategic planning.
