Hierarchical Visualization of Multidimensional Data

摘要

Visualization of multidimensional data has been studied for a few decades and is still hot today. However, the proposed approaches have limitations when they meet multidimensional data. Hierarchical approach proposed in this paper is utilized to represent multidimensional data in multi-levels. First, the dimensions that have not been visualized are divided into two parts. Then the first part of the dimensions is visualized in a lower dimensional space. Subsequently,the second part of the dimensions is inspected in the next levels. Repeat the previous steps and thus the data are visualized hierarchically in a few recursions.
