Foreign literatures from WOS platform were analyzed by bibliometrical methods and mapping domain knowledge of Citespace and Pajek. It was discovered that the research on knowledge visualization abroad involved many theories and methods in various disciplines. There were three research dimensions including technology realization,psychological cognition and knowledge management. The frontier researches have appeared in recent years involving four subjects: the construction of knowledge bases and knowledge service platforms,the application of knowledge visualization in education,psychological cognition mechanisms in knowledge visualization,knowledge management and decision- making. The application prospect of knowledge visualization in the discipline of library and information science is vast.
