Abstract The geographical information system represents a branch of information technology that was developed along with the traditional business information technologies. It enables viewing of complex data in a graphical manner easy to understand, providing a more realistic view of the conditions which must be evaluated. The geographical information systems are used in various fields, like geography, geology and all the related fields, public administration, military activities, transportation and infrastructure administration, business, healthcare, social services or land properties management. In this paper we will emphasize how these systems can be used as a powerful information visualization tool in educational environment, taking into account that information visualization makes data easier to understand using direct sensory experience, especially the visual one.

Information Visualization is a field of computer graphics which aims to present information graphically, allowing users to better understand a great amount of information. It also allows identifying standards, or even detecting new information which, at first, was not possible to be perceived due to its complex representation. This study briefly describes this field and presents a tool for visual data mining executed on the web, through of the Parallel Coordinates technique, that allow users to analyze information structured in a master/detail format. Other advantage of the tool is its capacity of accepting data from several systems exported by the user in the XML format. A case study is demonstrated in order to exemplify the resources of the tool.

Evaluation of information visualization and especially visual information systems is challenging. Metrics and methods need to be chosen with the intend of gaining specific and relevant evaluation data to prove the value of such systems. We suggest an evaluation based on the Information Service Evaluation Model (ISE) for information systems with visual result representation. We present the results of a case study on the testing and implementation of a visual search engine in business.

In many domains, it is important to understand both the topology and geography of a network. E.g., for researchers it is important to understand the topics in a field, where this research is taking place, and which researchers collaborate. Geography plays a key role in collaboration as it is more feasible with physical proximity. Researchers are also likely to continue existing collaborations. The interplay between topology and geography is of particular interest. Within Institution collaborations are different in nature from far-distance collaborations, as long-distance collaborations often occur less out of convenience but for more complementary expertise. These long distance collaborations can connect otherwise separate social groups. However, existing approaches either focus on the geospatial location of researchers, or on the social aspect of collaborations alone. We present GeoSocialVis, an interactive visualization tool for scientometrics analyses with a focus on displaying the geosocial co-authorship network. GeoSocialVis uses a novel force layout that strikes a user-defined balance between showing network topology and the geographic locations of the authors. Users can explore relevant publications, researchers, groups, and institutions by adjusting the balance between topology and geography, searching by keywords, and with details-on-demand. We demonstrate the utility of GeoSocialVis with a case study with IEEE Information Visualization 2008–2018 publication data.

RESUMO Refletimos sobre a importância dos infográficos e da visualização da informação, questões- chave do design da informação. Os infográficos são tipos de representação gráfica complexa que facilitam o entendimento do conteúdo; essas representações vêm sendo utilizadas crescentemente nos mais variados ambientes informacionais. Apresentamos um levantamento conceitual e histórico da infografia, identificando os atores envolvidos na produção infográfica. Apresentamos também a teoria e a metodologia da sintaxe gráfica de Engelhardt, com o objetivo de oferecer ferramentas capazes de identificar os mecanismos presentes nas representações gráficas em geral - este foi o método escolhido para a realização do estudo de caso proposto na presente pesquisa. Na análise, constatamos o uso adequado dos objetos gráficos na peça gráfica avaliada como um todo, começando pela escolha da tipografia que privilegia a legibilidade e também na escolha das cores utilizadas. Pudemos identificar todas as estruturas básicas de sintaxe do método utilizado; as relações entre objetos foram utilizadas adequadamente (agrupamento, separação, alinhamento, vinculação, contenção e sobreposição), além do uso apropriado do espaço significativo da página para distribuição do conteúdo. As escolhas assertivas da equipe de desenvolvimento possibilitaram a visualização de uma unidade na peça, criando hierarquia das informações a partir de variações nos atributos visuais tipográficos e nas representações pictóricas utilizadas. Além disso, no que diz respeito ao significado dos objetos gráficos, identificamos uma predominância no uso dos objetos informativos e referenciais, e poucos objetos decorativos - um fato que valoriza a matéria, tornando-a mais funcional pela escolha de objetos que são essenciais na produção de conhecimento por parte do leitor.Palavras-chave: Design da informação; Infográfico; Representação gráfica; Visualização de dados; Ciência da informação.               ABSTRACT We reflect on the importance of infographics and information visualization, key issues for information design. Infographics are types of complex graphic representation that facilitate understanding the content; these representations are being increasingly used in various information environments. We present a conceptual and historical survey of computer graphics, identifying the actors involved in infographic production. Presented here is the theory of Engelhardt's graphic syntax, in order to provide tools to identify the mechanisms in graphic representations in general. This was the method chosen for the case study proposed in this research. In the analysis, we found the proper use of graphic objects in the graphical part evaluated as a whole, starting with the choice of typography that focuses on readability and also the choice of colors used. We were able to identify all the basic structures of syntax of the method used, relations between objects were used properly (grouping, separation, alignment, bonding, containment and overlap) as well as the appropriate use of significant space on the page to distribute content, producing a unity in the piece while creating a hierarchy of information from variations in the typographical visual attributes and the pictorial representations used. Furthermore, as regards the meaning of the graphic objects, we identified a predominant use of reference information and few decorative objects, making it more functional for the choice of objects that are essential in the production of knowledge by the reader.Keywords: Information Design; Infographics; Graphic representation; Data visualization; Information science.
