You can decide on the visual representation of nodes belonging to all the treemap levels using the e-itemsLayoutMode property of the TreeMap.

There are four different TreeMap layouts such as

Squarified
SliceAndDiceAuto
SliceAndDiceHorizontal
SliceAndDiceVertical

Squarified

Squarified layout creates rectangles with best aspect ratio.
