| Abstract: | 2D graphical representation which reflects high-dimensional observation with sole point is one important branch of 2D graphical representations. The representation is competent for feature selection and class space building as it can display a set of observations in one graph. In this paper, the typical representations are analyzed according to the relationship between the sole point and number of attributes. The advantages, disadvantages of each representation and its applicability are also discussed. |

| Keywords: | graph representation with sole point high-dimensional data polar mapping scatter constellation graph |
