Example

Treemap with Ovals is tree visualization method proposed by Brian Johnson in 1993.

Visual Elements

The nodes of Treemap with Ovals is ellipse. The links of Treemap with Ovals is hidden.

Coordinate System

The coordinate system of Treemap with Ovals is cartesian coordinate system.

Layout

Treemap with Ovals is a hybrid tree visualization of Slice and Dice layout method.

      - Slice Layout

      Along the x axis, the relation between root and subtree group is include. The relation among subtrees within subtree group is flatten.

      Along the y axis, the relation between root and subtree group is juxtapose. The relation among subtrees within subtree group is flatten.

      - Dice Layout

      The relations along the axis in Dice layout is symmetrical to Slice layout.
