Graphic visualization of complex hierarchy data

A computer-implemented method can receive a hierarchy table comprising a plurality of records associated with objects organized in a hierarchical structure. The records comprise values corresponding to a plurality of displayable fields and specify value distributions among the objects. The method can specify one or more viewable fields at an input area of a graphical user interface, and display a plurality of nodes and a plurality of directional links connecting the displayed nodes on a display window of the graphical user interface. The displayed nodes represent objects whose associated records have unique combinations of values corresponding to the specified viewable fields. The directional links represent value distributions among objects represented by the displayed nodes. The method can display aggregated value distributed to or from objects represented by the displayed nodes. The viewable fields specify which of the displayable fields are visible on the displayed nodes.
