Abstract: In order to extract useful data from the mass data for users to analyse, this paper combines visualization technique with data mining technology by the thorough research of data visualization and clustering analyses, develops a visual data mining system in Java platform, and the result of data mining is displayed to users in the way of scatter 3D plot and parallel coordinates figure, so users can see the whole data set, and analyse the distribution of the same attribute value of each object and relationship between each attribute, thus, it can effectively express the results of data mining.

Key words: data mining, clustering analysis, visualization, parallel coordinates
