    Strata treemaps



    Treemap is a method of visualization to recognize a hierarchical structure of data using the size and arrangement of nested rectangles. A limitation of a treemap is the difficulty to discern the structure of a hierarchy. Several approaches have been proposed to improve the visibility of the hierarchical structure. These approaches involve the use of a border or padding to emphasize the hierarchical structure. However, this leads to a disparity between the node weight and the relative node size.
