Abstract:
Applying visualization to manipulate a large volume of data constitutes a current demand of professionals and researchers. Visualization stimulates human perception and increases the understanding capacity. In literature, there are many studies on the use of visualization in different areas, as well as tools that make its use feasible. Aiming to facilitate user’s comprehension, the objective of this paper is to explore, in the tree-map visualization, the combined use of the following functions: search, edit, data regrouping and hyperlink. This proposal was derived from two real problems: 1) to standardize a great volume of educational assessment questionnaires that could not be processed automatically; and 2) to analyze the dependencies among the TMMi (Test Maturity Model Integration) process areas, having simultaneous access to the text of all the ones related to a specific issue. The functions were implemented in the SeEd-Visual tool (Search and Edition based on Visualization), and
organized in a process that aims to enhance user’s comprehension through a visual metaphor. The process and the tool were applied to the real problems and allowed their solution. The use of visualization enabled the solution of the real problems since it would be hard if done manually.
