Compared with 2D technology, the 3D visualization and 3D mapping could provide a new technical methodology for information visualization, knowledge visualization and science mapping. In this article, the 3D visualization and 3D mapping are realized by using software tools Mage and Mayavi while drawing 3D graph. The 3D graph can rotate and move in the space for visualizing knowledge structure, with keeping 3D drawing three theorems. Two cases are shown in the article: one case is the two layers network; the other belongs to three layers network. With the revealing of the 3D core structures of multilayer networks, the information and knowledge visualization and science mapping have the potential to be promoted.
