3) suggest that data visualization assists in the constructing of hypotheses.ĭata visualization often results in graphical images of data or concepts, which assists making decisions (Ware, 2012). In this regard, Gray, Mayer, and Hughes (cited in Ware, 2012, p. The fourth is that it enhances the understanding of large-scale and small-scale data. The third advantage is that it can be used for product quality control where the immediate identification of problems is made possible through the data analysis. patterns) in the data immediately for formulating new insights. Secondly, it enables viewers to identify emergent properties (e.g. To begin with, it has the ability to represent a vast amount of data immediately. Traditional data visualization has a number of advantages. In this book, data visualization that focuses on the communication for understanding data rather than any other approaches is considered as traditional data visualization. In particular, the development of computer software has advanced the application of data visualization, allowing users to manipulate a substantial amount of data for exploration and analysis in an easier and more affordable way. The technology of data visualization has evolved from using hand drawing in the earliest stages, to “photo-etching”, to using computer technology, such as computing graphics and software (Friendly, 2009). As an emerging field, it is considered a sub-classification of visualization and is regarded as “the science of visual representation of ‘data’” (Friendly, 2009, p. Data visualization is usually associated with the field of computer science in the contemporary society. Data visualization has become an important part of research in many fields including algorithms, human perception, animation, computer vision and so on. Data analyst has become quicker and more accuracy using computer graphical data visualization. The invention of computer technology makes the huge change on the way of visual representation of data. Data visualization has significantly contributed to invention and discovery throughout human history (Crapo, Waisel, Wallace, & Willemain, 2000). At the ancient society, drawings and other visual representations were used to investigate the world and also to record the historical events. The term “data visualization” has a long history dated back the 2nd century AD.
