1. High dimensional Data Visualization using Star Coordinates on Three Dimensions Elio Lozano and Edgar Acuna Department of Mathematics University of Puerto Rico at Mayaguez

6. 2D Star Coordinates plot of Iris data set

7. Enhanced 2D Star Coordinates of Iris data set with polygons and labels

8. Here the three dimensional vectors a 1 ,…a n represent the axes. Collinear points are mapped to the same point using star coordinates in three dimensions. To avoid this overlapping we introduce new parameters to represent uniquely transformed points Three dimensional Star Coordinate Transformation where: A data point D j =(d j1 ,….d jn ) is mapped on the 3 dimensional point P j given by
