This course is designed to equip students with the knowledge and skills necessary to visualize, interpret, and communicate global trends using data visualization techniques. We discuss strengths and weaknesses in communication through data visualizations. During the course, students will acquire skills in data visualization through creation of plots, maps and animations. A key component in visualization of global trends is data of good quality. The students will explore where to find and how to obtain relevant data. Software used for preprocessing and visualization of data includes R and associated packages. Other modern tools for large and complex datasets can also be included. Students learn how to create compelling visual representations of global trends that facilitate understanding and decision-making, using real-world case studies on, for example, economic and social indicators and environmental and technological shifts.
