| Abstract | |
With the growing number and types of data, the need to analyze and understand what they represent and how they are related has become crucial. Visualization techniques based on multidimensional projections have gained space and interest as one of the possible tools to aid this problem, providing a simple and quick way to identify patterns, recognize trends and extract features previously not obvious in the original set. However, the data set projection in a smaller space may not be sufficient in some cases to answer or clarify certain questions asked by the user, making the posterior projection analysis crucial for the exploration and understanding of the data. Thus, interactivity in the visualization, applied to the users needs, is an essential factor for analysis. In this context, this master projects main objective consists to create visual metaphors based on attributes, through statistical measures and artifacts for detecting noise and similar groups, to assist the exploration and analysis of projected data. In addition, it is proposed to make available, in Web browsers, the multidimensional data visualization techniques developed by the Group of Visual and Geometric Processing at ICMC-USP. The development of the project as a Web platform was inspired by the difficulty of installation and running that certain visualization projects have, mainly due different versions of IDEs, compilers and operating systems. In addition, the fact that the project is available online for execution aims to facilitate the access and dissemination of technical proposals for the general public. (AU) | |
