A method and a system are described that involve generating a graphical tree hierarchy of a data structure and its accompanying metadata. In one embodiment, the method includes building a graphical tree hierarchy with a plurality of levels, wherein the graphical tree hierarchy includes at least a root node, a plurality of non-leaf nodes, and a plurality of leaf nodes. Further, the method includes aggregating at least a portion of the plurality of non-leaf nodes at a level of the graphical tree hierarchy, if a subset of the plurality of non-leaf nodes residing at the level exceeds a maximum number of nodes per the level. The method also includes scaling down the plurality of leaf nodes, if the plurality of levels of the graphical tree hierarchy exceeds a maximum number of levels.
