This thesis investigates the role of data visualization as a tool for the effective communication of statistical information, focusing on the intersection between statistical information and visual communication. The primary objective of the study is to examine how different design approaches influence audience comprehension, trust, and interest in data, while also highlighting the differing priorities of statisticians, visual content creators, and the general public. The research adopts a mixed-methods approach. First, a literature review is conducted on the historical development of charts and graphs, the principles of visual communication, and best practices in data visualization. This is followed by a case study of the Hellenic Statistical Authority (ELSTAT), aimed at evaluating the presentation of official statistical data under conditions of strict scientific neutrality. Finally, a quantitative survey is conducted through a questionnaire administered to a sample of 344 participants, including statisticians, graphic designers, and members of the general public. The findings indicate that the effectiveness of a visualization does not depend solely on its aesthetic quality or on the completeness of the data it presents. More detailed visualizations enhance users’ understanding and sense of certainty, whereas more creative and emotionally engaging approaches contribute to attracting interest and facilitating the dissemination of information. At the same time, statistical literacy, professional background, and familiarity with charts significantly influence the way users perceive, evaluate, and trust data visualizations. In conclusion, effective data visualization emerges from a balance between statistical accuracy, visual storytelling, and audience needs. The selection of an appropriate method for presenting data should take into account not only the characteristics of the data itself but also those of the intended audience, in order to maximize comprehension, trust, and meaningful engagement with the information.
