A simple jQuery plugin to create a tree map view of json data.

1. Import the script. Then your jQuery objects will have a new function.

   $('div#someId').treemap([]);

2. The json should have the follow format.

   $('div#someId').treemap(
   [
       {
       label: 'Label of treemap node',
       value: 100, // A number that defines the size of the node into the tree map.
       data: 'some arbitrary data. Can be a string'
       },
       {...} // This is a list
   ]);

1. Customizing the looking and feel.

You can pass a second parameter containing some options to customize the looking and feel of the tree map.

$('div#someId).treemap(
    [],
    {
        backgroundColor: function(node){
            //node is an item of the list passed as the first arg of this fuction;
            return 'red'; // You should return a css valid color string.
        },
        color: function(node){
            //node is an item of the list passed as the first arg of this fuction;
            return 'red'; // You should return a css valid color string.
        },
        nodeClass: function(node){
            //node is an item of the list passed as the first arg of this fuction;
            return 'my-class'; // You should return your customized css class here.
        }
    }
);

1. Customizing the events

You can alsa pass functions to deal with events related to mouse.

$('div#someId).treemap(
    [],
    {
        click: function(node, event){
            // click on a node
        },
        mouseenter: function(node, event){
            // mouse enter a node
        },
        mouseleave: function(node){
            //mouse leaves a node
        }
    }
);
