We live our lives surrounded by data. Mobile phones track our location, websites capture our habits, and social networks record our interactions. Yet a great deal of this data remains meaningless. This course merges the best practices of information design and interaction design to explore various ways of generating interactive visualizations of data. Participants learn how to apply design principles including knowledge of human perception, color theory, and effective storytelling, to data visualization. Students who want to present data to others, aspire to work with data scientists, or want to become more technically proficient with visualization tools, will grow their skills in this course.
