Data Visulaization with ggplot

Course overview

Creating clear and effective data visualizations is an important skill for any data scientist. This course will teach participants the key principles of data visualization and how to use the ggplot2library, along with useful extensions, to create high-quality plots efficiently. After completing the course, participants will have a strong understanding of how to make engaging and accessible visualizations. We will discuss the main concepts of the grammar of graphics and use hands-on examples to explore ggplot2’s utility to create multi-layered, more complex graphs.
