Classification tree analysis is one of the main techniques used in Data Mining, and nowadays there is a lack of a visualization method that support this tool. Therefore, graphical procedures can be developed in order to help simplify interpretation and to obtain a better understanding. This paper proposes a method for representing the input data for each class presented in each terminal node. For this purpose, the new visualization method Sectors on Sectors (SonS) is used. The methodology is tested in two real data sets.
