Scatterplot is one of the most popular techniques for multi-dimensional data
visualization. However, it is not always easy to effectively represent the
multi-dimensional spaces by scatterplots. Various dimension reduction and
scatterplot matrix (SPM) techniques have been presented to effectively
represent them in a single display space. Also, various interactive
techniques such as ``Rolling the Dice'' have been presented to assist the
visual analytics processes. We discuss a technique to represent
multi-dimensional spaces using multiple scatterplots like SPM-based
techniques. Here, SPM-based techniques has a drawback that each of the
scatterplots will displayed very small when all pairs of dimensions are
equally displayed. On the other hand, our technique presented in this poster
selectively displays a set of meaningful pairs of dimensions, instead of
displaying all pairs of dimensions. It calculates scores of pairs of
dimensions, and selects pre-defined number of pairs of dimensions. Then, it
defines the distances or connectivity of the scatterplots generated from the
selected pairs of dimensions, and calculates their ideal positions based on
the distances or connectivity. Finally, it places the set of scatterplots by
a rectangle packing algorithm referring their ideal positions. Consequently,
the technique places similarly looking scatterplots closer in the display
spaces. It is useful to understand the correlations among many dimensions.
