This paper presents a comprehensive visual analysis of the literature on systemic functional linguistics from 2003 to 2023 using the CiteSpace6.2.R4 knowledge graph analysis tool. By examining core journals in CNKI and Web of Science, the study explores publication, authors, institutions, and keywords to provide a detailed overview of the field. The findings reveal that systemic functional linguistics continues to attract significant attention from scholars globally. The analysis of research authors and institutions highlights active contributors both domestically and internationally, with Sun Yat‐sen University representing the domestic institutions and the University of Sydney representing the foreign institutions. Moreover, the study identifies cross‐ disciplinary, multi‐dimensional, and practical development trends as the primary research hotspots in systemic functional linguistics.
