How to do it...

In this recipe, let's see how we can implement an enclosure diagram using d3.pack:

function pack() { 
        var _chart = {}; 
 
        var _width = 1280, _height = 800, 
                _svg, 
                _valueAccessor, 
                _nodes, 
                _bodyG; 
 
        _chart.render = function () { &...
