Abstract The non-linear structure of high-dimensional data cannot be captured by the existing radial layout visualization method. Therefore, visual clustering method of quasi-circular mapping based on dimension extension and rearrangement is proposed. The dimension of high-dimensional data is expanded by affinity propagation clustering algorithm and multi-objective clustering visualization evaluation index. Then, the dimension correlation rearrangement of the extended high-dimensional data is carried out. Finally, the high-dimensional data is reduced to two-dimensional visualization space by quasi-circular mapping mechanism to realize effective visual clustering. Experiments show that the proposed dimension extension and rearrangement strategy can effectively improve the visual clustering effect of quasi-circular mapping visualization. The dimension extension strategy can also significantly improve the clustering effect of other radial layout visualization methods with better generalization performance. Moreover, the proposed method has obvious advantages in visual clustering accuracy, topology
