  Network theory provides tools which are particularly appropriate for
assessing the complex interdependencies that characterise our modern connected
world. This article presents an introduction to network theory, in a way that
doesn't require a strong mathematical background. We explore how network theory
unveils commonalities in the interdependency profiles of various systems,
ranging from biological, to social, and artistic domains. Our aim is to enable
an intuitive understanding while conveying the fundamental principles and aims
of complexity science. Additionally, various network-theoretic tools are
discussed, and numerous references for more advanced materials are provided.
