(Color online) Screenshot of the Rank-Vis system for visually analysing the pesticide-residue dataset selected in the parameter panel (E). (${\rm~A}_1$) The row and column vectors in matrix $A$ are ranked in alphabetical order. (${\rm~A}_2$) Matrix $B$ is the same matrix with the row and column vectors reordered by the proposed RW-Rank algorithm. (${\rm~B}_1$) and (${\rm~B}_2$) are the word clouds, in which the sizes of the pesticide and agricultural product names are mapped to the detection and pesticide residue detection frequencies, respectively. (C) Pie chart showing the percentages of four residue levels (levels 1, 2, 3 and undetermined) in different agricultural products selected by clicking their names in (${\rm~B}_1$). (D) Parallel coordinate shows the detailed information of a specific agricultural product selected by clicking its name in (${\rm~B}_2$).
