| GraphManager | The GraphManager is used to manage and render a Graph |
| LayoutRectangle | Helper structure for the bounds of a node/layout |
| TreeMap | The TreeMap is used to manage and render a TreeMap with a specified layout |
| TreeMapItem | The TreeMapItem represents one node of a TreeMap |
| TreeMapItemInfo | Item structure that holds information about a node |
| TreeMapLayout | Interface for a layout algorithm |
| TreeMapSliceLayout | Slice and Dice layout. Area of parent node is split up into parts of the same size |
| TreeMapSquaredLayout | Squared layout. The algorithm tries to get aspect ratios close to 1 for all child rectangles |
| TreeMapStripLayout | Strip layout. Similar to the squared layout algorithm, but keeps neighbor relationships between child nodes. The aspect ratios are not as good as with the squared layout algorithm |
