This thesis aims to explore options for teaching visual literacy at the high school level using an interactive digital game format. In this thesis, the concept of visual literacy will be explored, especially with a focus on contemporary approaches to education by using video games. The benefits and constraints of utilizing serious games for educational purposes in the context of visual literacy will be highlighted. As a result of this research, an educational game prototype will be designed and developed to improve visual literacy by explaining commonly used visualization techniques such as Line Chart, Area Chart, Stacked Area Chart and Stream Graph. The resulting game should demonstrate the technical feasibility of these concepts and their uses.
