jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxTreeMap is used for showing the hierarchical data set of nested rectangles. Here each and every branch of the tree is represented as a rectangle, which is then tiled with smaller rectangles that represent sub-branches. Here the rectangle of the leaf node has an area proportional to a specified dimension on the data.
The render() method is used for rendering the specified jqxTreeMap widget.
Syntax:
$('#jqxTreeMap').jqxTreeMap('render');
Parameters: This method does not accept any parameters.
Return values: This method does not return any values.
