Hot spot analysis of big data visualization research in China based on co-word network

Big data visualization is a rapidly developing field, and various new technologies and methods continue to emerge, making big data visualization widely used in various fields. With the advancement of technology and the expansion of application scenarios, big data visualization will continue to play an important role in the future. This paper adopts the co-word network analysis method to conduct bibliometric analysis of the relevant research of big data visualization in China from 2012 to 2022, identifies the hot spots and connection points in the field of big data visualization in China by drawing a knowledge network map, shows the research structure of big data visualization through visual analysis, and predicts the future research development trend on this basis. The results show that seven knowledge points, such as "data analysis", " visualization analysis" and "big data technology", are the current research hotspots in the field of big data visualization, which determine the development direction of future research.
