Models help us navigate the complexity of social life, offering simplified structures that make invisible dynamics legible. Networks stand out for their ability to represent relations directly: nodes and links reduce society to actors and their connections, exposing patterns that often remain hidden in linear accounts. Since the eighteenth century, networks have evolved from mathematical curiosities to essential tools across disciplines. Early sociograms revealed classroom friendships, sociological diagrams exposed social reproduction and inequality, and computational studies now map everything from recipes to scientific collaborations. With their visual grammar, networks invite comparison, clustering, and interpretation across diverse domains. Yet their ubiquity also introduces risks: layouts may be mistaken for objective spaces, central nodes assumed to be more important, and dense graphs admired more for aesthetics than insight. To address these challenges, a new form of literacy is required. Network literacy can be defined as the ability to understand, design, and read visual relational models, combining conceptual knowledge of complex systems with practical skills of visualization and critical interpretation. This paper develops the notion of network literacy as a civic and professional competency, bridging traditions of data literacy and visual literacy. It traces the history of networks from their mathematical and sociological origins to their integration into digital media and design, showing how they reconfigure the codex into a relational mode of reading. It then explores three dimensions: design choices that shape meaning, spatial thinking that guides interpretation, and experimental projects that turn visualization into performative practice. By situating networks at the intersection of information design, critical inquiry, and cultural practice, the paper argues that cultivating network literacy is essential for engaging responsibly with the relational fabric of contemporary knowledge.
