MIT: Concept Mapping Tool
By mapping out ideas the ability to more fully understand connections reveals otherwise unnoticed details.
This open source project, Interactive Concept Maps, allow users to create maps for courses, projects, and career planning. The first and most complex problem in creating this web application was making the visualization or organization easy and quick to understand. This problem was solved by making the entire canvas clickable, with each click adding a new node. While a dragging feature allows the user to connect nodes to create parent, siblings and other relationships.
