Web Based Time-Tunnel: An Interactive Multidimensional Data Visualization Tool Using Genetic Algorithm

This paper presents a Web based Time-tunnel, a visualization system that renders 3D charts of time series multidimensional data in a web browser. The system supports to find differences and similarities among several data by overlapping their charts together. Nonetheless, if many charts are overlapped, it can be difficult to distinguish the charts. Therefore, the authors added new functionality to the system that optimizes data classification by using genetic algorithm, and then, the system came to visualize several charts of data as one group those have a strong relationship among them. In addition, users can share the visualized result with other users by specifying URL generated by the system. In this paper, the authors also justify the usability of the system by indicating visualization results of actual data.
