Method and system for providing graphical user interface for displaying hierarchical charts. According to various embodiments, the present invention provides a graphical user interface where relational data are displayed as one or more hierarchical charts. A hierarchical chart includes a plurality of nodes that are organized according to the hierarchical chart. Each of the nodes is associated with a data record that contains multiple level of information. At different view level, different amount of information for the nodes are displayed. A view control function is provided for the graphical user interface. If none (or all) of the nodes are selected, each nodes display the same level of information based associated with a particular view level. If only few of the nodes are selected, only the selected nodes responds changes in view level when being displayed.
