Conflicting Standards for Designing Data Displays: Following, Flouting, and Reconciling Them    

Standards for designing data displays—for example, bar graphs, line graphs, pie charts, scatter plots—can be classified into four types: Conventional—emphasis on imitating generic forms that meet readers’ expectations. Perceptual—emphasis on optimizing reader behavior in accessing data visually. Informational—emphasis on transferring information clearly and concisely from designer to reader. Aesthetic—emphasis on taste, cultural values, and expressive elements. While each of these standards has merit, and some overlap occurs among them, they often conflict with each other, leaving the information designer in a quandary as to which standard to follow. Designers can resolve this dilemma by allowing the rhetorical situation—the readers of the display, its purpose, the context in which they use it—to guide the design process, telling designers when to follow, blend, or flout the standards.

From Pen to Print: The New Visual Landscape of Professional Communication     

Visual design has played an important role in the historical development of professional communication. The technology of laser printing has reestablished the importance of visual language in functional communication, transforming contemporary document design and redefining its relation to the traditions of handwritten, typewritten, and printed text. During this period of transition, three factors will shape the new visual language: (a) the development of a visual rhetoric that represents design as an integral part of the message rather than merely as external "dress," (b) the rediscovery of aesthetics as a legitimate factor in text design, and (c) the use of empirical research--particularly context-specific research--to guide the document design process.

Supra-Textual Design: The Visual Rhetoric of Whole Documents    

Supra-textual design encompasses the global visual language of a document and operates in three modes: textual, spatial, and graphic. The rhetoric of supra-textual design includes structural functions that provide global organization and cohesion and stylistic functions that affect credibility, tone, emphasis, interest, and usability. Supra-textual rhetoric extends to other documents through conventional codes and through sets and series. Because writers may not control the end product of supra-textual design, intention may also be a rhetorical factor.

A Systematic Approach to Visual Language in Business Communication    

Although business communication relies heavily on the visual, current approaches to graphics and text design are prescriptive and unsystematic. A 12-cell schema of visual coding modes and levels provides a model for describing and evaluating business documents as flexible systems of visual language. Emphasizing clarity and objectivity, the 'information design' movement has generated guidelines for creating functional visual displays. However, visual language in business communication is seldom rhetorically 'neutral' and requires adaptation to the contextual variables of each document, a goal the writer can achieve by com bining visual and verbal planning in the same holistic process.

Typographical Design, Modernist Aesthetics, and Professional Communication    

The technology of in-house publishing is radically shifting the responsibility for document design from the graphic specialist to the individual writer. To apply the new technology, professional communicators need to understand the principles underpinning typographical design and their origin in the functionalist aesthetics of modernism, particularly as articulated by the Bauhaus. While some of the key concepts of modernism--strict economy, universal objectivity, intuitive perception, and the unity of form and purpose--are well-suited to business and technical documents, these concepts are bound to an historical and intellectual milieu. By understanding the influence of modernism on typographical design, professional communicators equipped with the new technology can adapt design principles to the rhetorical context of specific documents.
