A method, apparatus and computer-readable medium for generating a graphical tree based on a hierarchical structure includes receiving a request to convert a first hierarchical structure into a first graphical tree. Each of a plurality of elements of the first hierarchical structure, and the relationships among the plurality of elements are identified. A first graphical tree is generated based on each of the plurality of elements and the relationships among the elements. The first graphical tree is then displayed. Additional graphical trees can be displayed simultaneously and associations between nodes of the different graphical trees can be designated.
