The available layout types are,
- Squarified
- SliceAndDiceVertical
- SliceAndDiceHorizontal
- SliceAndDiceAuto
Squarified
The Squarified
layout displays the nested rectangles based on aspect ratio in the TreeMap. The rectangles will be split based on the height and width of the parent. The default rendering type of layout is Squarified
.
