Abstract: We consider the problem of illusory or artefactual structure from the vi-sualisation of high-dimensional structureless data. In particular we ex-amine the role of the distance metric in the use of topographic mappings based on the statistical field of multidimensional scaling. We show that the use of a squared Euclidean metric (i.e. the SSTRESS measure) gives rise to an annular structure when the input data is drawn from a high-dimensional isotropic distribution, and we provide a theoretical justifica-tion for this observation. 1
