Abstract: This paper combs the existing within-document visualization analysis tools. According to the differences of visual objects, these tools are divided into three types, based on within-document lexical distribution visualization, based on within-document semantic structure visualization, and based on within-document topic visualization. Then twelve kinds of typical tools are analyzed in detail and compared from the applicable documents, text analysis method, visual representation, visual object, interaction, advantages, limitations and other aspects. And thus this paper summarizes the characteristics of three types of tools, the differences and similarities. Finally, some suggestions for the development of the existing within-document visualization analysis tools are proposed, which aim to provide reference for researchers.
