Big data applications, as well as the whole myriad of applications arisen through the evolution of the body of knowledge commonly known as Data Science brings new challenges to CS-related courses curricula. The demands imposed in CS-related courses by the recent development of data-oriented application makes that visualization skills became an important part of both undergraduate and graduate formation. In this sense, this paper presents a syllabus for a Knowledge Visualization course, adaptable to both undergraduate and graduate levels, which aims to contribute to systematize the competences, skills and attitudes regarding data, information and knowledge visualization that are expected to be developed by future professionals.
