With the rapid development of the scale of complex network, such as WWW network, social network, the traditional way of text and form to describe network can not meet the requirement of analyzing and managing the growing power of network data, but as an effective method to assist us in understanding the structure of networks and mining useful information, visible technology are widely applied. Choosing the literature of the theme on the complex network visualization in Web of Science database as the studying object, map out the knowledge maps of the reach field by using Citespace. The result showed the major countries、institutions and Core Journal; revealed the evolution paths of complex network visualization research from theory research to empirical research, exploring methods to the practical application; pointed out the reach hotspots were visualization tool, algorithm etc; the reach fronts were social network analysis, data mining etc. This paper can provide valuable reference for faster and better understanding the intellectual bases and research progress of the complex network visualization.
