This study examines data visualization as a form of cultural rhetoric that actively shapes persuasion, communicates uncertainty, and constructs trust within contemporary information ecosystems. Moving beyond the view of visualization as a neutral technical tool, the paper situates visual representations within broader cultural, social, and institutional contexts that influence how meaning is produced and interpreted. It explores the theoretical foundations of visual rhetoric, emphasizing how narrative framing, visual encoding, and aesthetic choices function as persuasive mechanisms that guide audience perception and judgment. The analysis highlights the role of cultural codes and interpretive frameworks in mediating meaning, demonstrating that visualizations are inherently embedded in systems of belief, values, and social norms. Particular attention is given to the communication of uncertainty, where techniques such as confidence intervals, variability indicators, and dynamic representations are often unevenly understood across cultural contexts, leading to risks of overprecision or misinterpretation. The study further investigates the dynamics of trust, focusing on provenance, credibility, transparency, and reproducibility as key determinants of audience confidence in visual data. Through case-based insights from public health, environmental communication, and economic policy, the paper illustrates how visualizations influence public discourse, decision-making, and institutional legitimacy. Ultimately, it argues for a culturally responsive and ethically grounded approach to visualization design, supported by interdisciplinary methodologies and enhanced data literacy, to ensure that visual communication remains both persuasive and trustworthy in complex, data-driven societies.
