Composition in Traditional Chinese Paintings (TCPs) carries spatial, narrative, and cultural-aesthetic meaning. Systematic compositional analysis is therefore important for understanding their visual language and artistic meaning. Traditional compositional analysis is mainly qualitative and interpretation-driven. It supports close reading of individual paintings, but it is difficult to discover, compare, and verify compositional patterns across large painting collections. To better understand these challenges, we conducted a literature review and in-depth interviews with two art historians. Based on these findings, we introduce the Composition Graph, a scene-graph-based representation for TCP composition. It models a painting through four layers: entities, relations, void space, and context. Based on this representation, we develop CompoVista, a canvas-based visual analytics system for composition-oriented exploration of TCPs. CompoVista allows art historians to construct and revise format-aware painting cohorts through visual queries and context queries. It also supports cohort-level inspection of entity distributions and relations, comparison of compositional differences across cohorts, and tracing aggregate patterns back to painting-level evidence.We evaluated CompoVista through a task-based user study with 12 domain participants, two case studies, and expert interviews. The results show that CompoVista supports composition-oriented cohort construction, pattern discovery, iterative refinement, and evidence inspection. The evaluation also reveals future needs, including clearer result explanations, fuzzier composition queries, and stronger exploration history management. Our work contributes a composition-specific structured representation and an integrated visual analytics workflow for studying TCP composition at collection scale.
