Abstract

Nowadays, visualization is used in all contexts. However, there is a gap or mismatch between the intensive use of visualization and our low level of visual knowledge. The creation and proper use of effective information visualizations is constrained by rules or principles that guarantee their effectiveness in communicating a message. Many of these principles come from psychology and, specifically, from the theory of perception. Other principles emerge from the structure of information and the visual power of tables and graphs. Despite all of these considerations, two key principles must be kept in mind when creating and using information visualizations within a communications strategy: the principle of objectivity and the principle of data-ink ratio.

Abstract

We offer some thoughts on the need for the field of open data to evolve from the production to exploitation stage. We detail the process of generating a simple display: knowledge of sources and data extraction, local analysis or in the cloud, and using the tools needed to present the data. Information is offered on free tools readily available on the Net that an information specialist should know. Finally, knowledge acquisition in the field of data is reinterpreted, and illustrated with an example, London: the information capital, that provides advanced visualizations based on open data.

Abstract

The implementation and global expansion of the internet has affected all areas of our society. This influence has forced the media to revise their business models by creating new production and distribution processes and ultimately pushing out new digital versions (online media or cybermedia) of their publications. In this new digital environment information visualization plays a key role in marketing plans and user retention. This trend can be further understood by exploring the distinction between infographics and data visualization, and by defining a taxonomy that describes all new and traditional information visualization products used in online media.

Abstract

Information visualization covers the basic functions of data storage and communication, and reasoning support; most of the recently developed visualizations include these functions. However, among these, a small subset stands out for their innovative approaches and contribution to the development of the discipline. This article will review some of the innovative visualizations developed in 2016 and organize them into three groups. On the one hand, we present a small selection of visualizations that incorporate conceptual novelties and new visual proposals. On the other hand, we show some others that have drawn attention to the importance of the data set they have visualized. Finally, we account for some of the technological advances that have been developed within the discipline throughout this year.

Abstract

Recent advances in technology have provoked changes in the information visualization discipline. This article reviews some innovative visualizations and organizes them into three groups. First, we present a small selection of visualizations that incorporate conceptual novelties and new visual proposals. Second, we show some other ones that have drawn attention to the importance of the data set they have visualized. Finally, we account for some of the technological advances that were made in 2017 within the discipline.

Abstract

2018 has been an important year for the information visualization discipline. This work reviews some of the innovative visualizations developed throughout 2018, organizing them, asd previous proposals published in this Anuario ThinkEPI, into three groups. First, a small selection of visualization with conceptual novelties and new visual proposals are presented. Second, there are some others that have drawn attention to the importance of the data set they have visualized. Finally, some of the technological advances that have been developed within the discipline throughout this year are highlighted.

Abstract

The aim of the paper is to serve as a gateway to the world of geographic information systems (GIS), seen as technologies t support decision-making services in libraries and information units. Through the review of various projects that make use of GIS technologies in libraries, the concept of GIS and its synergies with information units is introduced. Finally, the paper points out different contexts and situations, in relation to information units, in which GIS could be used to improve services and products by information professionals.

Abstract

This overview introduces and synthesizes some basic concepts of the broad spectrum of information visualization, providing examples with geospatial, relational and textual data from a demanding discipline. The concepts are discussed and the examples illustrate some practices and criteria.

Abstract

This paper presents a review of approaches to text visualization and exploration. Text visualization and exploration, we argue, constitute a subfield of data visualization, and are fuelled by the advances being made in text analysis research and by the growing amount of accessible data in text format. We propose an original classification for a total of 49 cases based on the visual features of the approaches adopted, identified using an inductive process of analysis. We group the cases (published between 1994 and 2013) in two categories: single-text visualizations and text-collection visualizations, both of which can be explored and compared online.
