Abstract(s)
Desde os primĆ³rdios da civilizaĆ§Ć£o, a humanidade lida com dados de diferentes naturezas, porĆ©m os avanƧos computacionais provocaram tanto a explosĆ£o de informaĆ§Ć£o, como o processo de a tornar interpretĆ”vel num determinado contexto. Com o desenvolvimento de um volume cada vez maior de dados, surge a necessidade de desenvolver e aprimorar tĆ©cnicas e ferramentas capazes de lidar com o armazenamento, processamento e apresentaĆ§Ć£o da informaĆ§Ć£o proveniente destas fontes. Dando resposta a estes desafios, as ferramentas grĆ”ficas evoluĆram tambĆ©m para analisar estes dados massivos, tornando a sua leitura mais amigĆ”vel. Estas ferramentas sĆ£o capazes de facilitar a deteĆ§Ć£o de anomalias nos dados, relacionamentos, padrƵes ou tendĆŖncias, tornando os pontos a avaliar mais evidentes nos grĆ”ficos selecionados.
Uma das problemĆ”ticas mais relevantes do estudo da visualizaĆ§Ć£o de informaĆ§Ć£o recai sobre a escolha das representaƧƵes grĆ”ficas adequadas para cada tipo de dados. Associar dados a elementos grĆ”ficos e a uma localizaĆ§Ć£o no espaƧo pode ser uma tarefa difĆcil que requer conhecimentos em tipos de dados, anĆ”lise de dados e representaƧƵes grĆ”ficas. TambĆ©m o storytelling se apresenta como um tema bastante preponderante na questĆ£o da apresentaĆ§Ć£o de informaĆ§Ć£o proveniente dos dados recolhidos, entrando em aĆ§Ć£o, frequentemente, a par da temĆ”tica da visualizaĆ§Ć£o de dados.
Como objetivo geral deste estudo, pretende-se o desenvolvimento de painĆ©is sobre a forma de dashboards que sejam capazes de transmitir a informaĆ§Ć£o presente numa base de dados considerada previamente (projeto UniBench) de forma que o utilizador final seja capaz de interpretar a informaĆ§Ć£o apresentada e responder a um conjunto de questƵes definidas a priori. Durante este processo serĆ£o tidas em conta as tĆ©cnicas de visualizaĆ§Ć£o adequadas para cada caso especĆfico e, consequentemente, as tĆ©cnicas de storytelling mais adequadas para contar a histĆ³ria desses dados.
No final do estudo foi possĆvel inferir que os utilizadores dĆ£o primazia Ć simplicidade de utilizaĆ§Ć£o e navegaĆ§Ć£o, sendo este um fator decisivo na sua escolha por determinada plataforma ou dashboard. Ć essencial que os tĆ³picos mais relevantes sejam de fĆ”cil acesso e que se apresentem bem visĆveis, devendo ser desenvolvido um esquema de navegaĆ§Ć£o conciso, cujo acesso aos dados seja coerente e que ocorra mediante processos semelhantes, de forma que o utilizador consiga identificar com facilidade a forma de resgatar determinados dados. Para finalizar, importa ressalvar que a histĆ³ria de dados deve sustentar os elementos visuais conferindo uma fonte adicional de suporte Ć navegaĆ§Ć£o pelos diferentes painĆ©is, complementando a informaĆ§Ć£o apresentada com a interpretaĆ§Ć£o do prĆ³prio utilizador.
Since the dawn of civilization, humanity has been dealing with data of different kinds, but advances in computing have triggered both the explosion of information and the process of making it interpretable in each context. With the development of large volumes of data comes the need to develop and improve techniques and tools capable of handling the storage, processing and presentation of information from these sources. In response to these challenges, graphic tools have also evolved to analyse this massive data, making it more user-friendly to read. These tools can facilitate the detection of anomalies in the data, relationships, patterns or trends, making the points to be evaluated more evident. One of the most important issues in the study of information visualization is the choice of appropriate graphic representations for each type of data. Associating data with graphic elements and a location in space can be a difficult task that requires knowledge of data types, data analysis and graphic representations. Storytelling is also a very important topic when it comes to presenting information from the data collected, and often comes into play alongside data visualization. The general aim of this study is to develop a dashboard capable of transmitting the information present in a previously considered database (UniBench project) in such a way that the end user is able to interpret the information presented and answer a set of questions defined previously. During this process, the appropriate visualization techniques will be considered for each specific case and, consequently, the most appropriate storytelling techniques to tell the story of the data. At the end of the study, it was possible to infer that users give priority to simplicity of use and navigation, which is a decisive factor in their choice of a particular platform or dashboard. It is essential that the most relevant topics are easy to access and clearly visible. A concise navigation scheme should be developed, with consistent access to data and similar processes, so that the user can easily identify how to retrieve certain data. Finally, it should be noted that the data story should support the visual elements by providing an additional source of support for navigation through the different panels, complementing the information presented with the user's own interpretation.
