Abstract: A multidimensional data visualization apparatus capable of visualizing a data distribution in an input space of high-dimensional data so as to enable understanding of relationships between input dimensions is provided. Low-dimensional parallel coordinates plot creation element 71 creates, from input multidimensional data, a plurality of low-dimensional parallel coordinates plots that are each a graph in which data relating to part of dimensions in the multidimensional data is represented by a parallel coordinates plot. Feature value computation element 72 computes, for each pair of low-dimensional parallel coordinates plots, a feature value indicating a relationship between the low-dimensional parallel coordinates plots forming the pair. Coordinate computation element 73 computes coordinates at which each low-dimensional parallel coordinates plot is arranged, based on the feature value computed by the feature value computation element 72.

Abstract: There is provided a multidimensional data visualization apparatus capable of visualizing the distribution of data in an input space of high-dimensional data so that the relationships between input dimensions can be seen. Subplot generation means 71 generates, from input multidimensional data, multiple subplots as charts representing data on some dimensions in the multidimensional data. Feature value calculation means 72 calculates the feature value of a relationship between paired subplots for each pair of subplots. Coordinate calculation means 73 calculates the coordinates, at which each subplot is placed, based on the feature value calculated by the feature value calculation means 72.
