Abstract: Considering the problems aroused by the traditional association rules visualization approaches which are orienting to expert users while ignoring the normal user perception,even more when the number of rules increases,particularly prone to overlap among edges and nodes,as well as result in reducing the performance and readability of rule representation,this paper proposed a novel form of visualization display method based on S-C metagraph to show one-to-one,one-to-many,many-to-many association rules．Firstly,gave the basic definition of S-C metagraph and the model showing association rules using S-C metagraph.Then gave the properties and derivation process of S-C metagraph for visualizing association rules．Finally,with the help of experimental data obtained from demographic data of a province,combining with the Preattentive Processing Theory and Gestalt Theory,we illustrated multi-mode association rules in the combination form of S-C metagraph and spindle,and analyzed the effect of the visualization display．The realistic application analysis and eperimental results turn out that the proposed visualization method has excellent visual effects.
