Abstract :
In data visualization, we graphically represent information to ultimately utilize more understanding from data and reveal more knowledge of hidden information from contents. We are surrounded by data of all kinds and forms, business, demographics, weather, Scientifics, medicine, financials, marketing, advertising and so forth. Human being internal model-cognitive map is generated based on what we observed. This internal model is not just big map but a large number of these for all different kinds of things. Moreover, visualization is inherently analytical and therefore, showing images and graphs in 3D is not enough. Data visualization should be part of process that allows the user to find the answer in his own mind while view of projection of the data that reduces the complexity and amount of data to capture important and essential information. To summarize, goal is, understanding of data that could be combined with visualization to provide quantitative overview of large and complex data sets, can summarize data, and can assist in identifying regions of interest with appropriate parameters for more focused analysis. It should harnesses the perceptual capabilities of human visual system.
