18 Nov 201814 minutes to read

Determine the visual representation of nodes belonging to all the TreeMap levels using the layoutType property.

Types of layout

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.

var treemap = new ej.treemap.TreeMap({
    dataSource: [
        {State:"United States", GDP:17946, percentage:11.08, Rank:1},
        {State:"China", GDP:10866, percentage: 28.42, Rank:2},
        {State:"Japan", GDP:4123, percentage:-30.78, Rank:3},
