A simple jQuery plugin for drawing squarified treemaps.

To use the treemap plugin all you need is jQuery and then you can include the treemap.min.js file on your page. Once you have the script included simply select the element you want to draw the treemap in and call the treemap() function with your data.

There are three fields that can be used for every node you intend to render in the treemap:

• Value (Required): the value of the node. If for some reason you want to use a property name other than Value, you can override the ValueField setting.
• Color (Optional): the color you wish to use for this node. If not specified a default color is used. If for some reason you want to use a property name other than Color, you can override the ColorField setting.
• Children (Optional): A list of additional nodes to render inside the main node. If for some reason you want to use a property name other than Children, you can override the ChildrenField setting.

A 1 pixel black border is used to separate the nodes. If you wish to change this you can override the Border setting.

Example

var list = [
				{
					Value: 24,
					Children: [{Value: 13}, {Value: 3}]
				},
				{
					Value: 21,
				},
				{
					Value: 13,
					Children: [{Value: 13}, {Value: 8}, {Value: 23}, {Value: 22}, {Value: 3}]
				},
				{
					Value: 5
				}
			];

var settings = {
  Border: '1px solid #ccc'
};

$('.treemap-container').treemap(list, settings);

Prequisites: Make sure you have npm and gulp installed.

Run npm install to install the required packages. Then simply make your changes and run gulp. The default gulp task will clean the dist folder, run the tests, then minify the code and publish it to the dist folder. If you'd like to check your work there's a treemap.html file included under the Demo folder that has an example set up.
