Do you like watching movies? This visualization of Khan Academy movies was designed and developed by Benjamin Wiederkehr, MA student in Interaction Design at the Zürich University of the Arts and designer at Interactive Things, with the support of Jérôme Cukier, a data visualization consultant based in France. The Khan Academy is an organization with the goal of changing education for the better by providing a free world-class education to anyone anywhere. All of the Khan Academy's materials and resources are available completely free of charge. This visualization shows the complete library of over 3,000 online videos and their organization in topics, subtopics, and playlists. The four main topics, ‘Math,’ ‘Science,’ ‘Finance & Economy,’ and ‘Humanities,’ together with their subtopics, form the center of the hierarchical structure. Connected to the topics and subtopics are the playlists and the contained videos. The size of the filled circle indicates the aggregated duration of the material and the size of the ring denotes the amount of views. The videos are represented with one bar showing duration and another bar showing the amount of views. Go online and learn at http://khanacademy.org
