The proposed platform is a multi-user web-based annotation system which allows users to make annotations on specified area of a figure to facilitate discussions on figure or graph. With the help of tree-like hierarchy annotations, which are organized in a tree structure, user can facilitate in-depth discussions on the same topic, or create new issues. By way of the proposed learning environment, many fields of collaborative learning concerning figures, graphs, multimedia animations are feasible online.
