Abstract

Systems and methods in accordance with various embodiments of the present invention provide for representing a plurality of data values of a hierarchical dataset as graphical elements in a configurable data visualization. A first data visualization may be displayed in a data visualization display page, along with a user interface. A selection of a rendered root node and rendered leaf nodes to be displayed in a second data visualization is received from the user interface. Based on the selection of the rendered root node and rendered leaf nodes, a number of depth levels to display is determined. Also, which of the depth levels to display are identified based on the selection of the rendered root node and rendered leaf nodes. The second data visualization is rendered based on the determined number of depth levels and the identified depth levels.
