From Harvard University's Center for International Development (CID) comes the Atlas of Economic Complexity. This long-running data visualization project "allows people to explore global trade flows across markets, track these dynamics over time, and discover new growth opportunities for every country." Intended for use by a broad audience, the atlas was originally launched as an online companion to the 2011 book The Atlas of Economic Complexity, and since then it has been updated repeatedly with new features, data, and visualizations. Visitors may like to start with the explore section, where they can enter search phrases such as "What did Colombia export in 2016?" or use on-screen filters to choose a combination of data to view in several different visualization options. Those interested in using the atlas for research should peruse the publications section to see examples of others' research using this resource, while the learn section contains key concepts and a forthcoming tutorial series. Developed and updated by a team of web developers, data visualizers, and research fellows overseen by Annie White, the Atlas of Economic Complexity is a product of CID's Growth Lab, which is directed by Professor of the Practice of Economic Development Ricardo Hausmann.
