Abstract: Based on the study of pesticide residues detection result data, which has the characteristics of geographical level and the level of classification of fruits and vegetables, in node links and radial loop algorithm visualization model, the double level structure, radiation chain graph CircleLink, was designed for analysis of pesticide residues data in visual modeling algorithm. The visual modeling algorithm was applied to the actual pesticide residues detection results data for the simulation analysis and conclusions. Analysis of the characteristics of pesticide collection, distribution of agricultural products and supermarket pesticide residues of pesticide residues was applied.

Key words: pesticide residues, node-link, radial ring, CircleLink
