OK, here's an extraordinarily hacky solution. Because we're reading the DOM, this solution actually *requires* that all of the labels are visible and not truncated, so that you can sanely correlate them with your data. So in its current state, this solution would not be usable for rects with very long names, or rects that wind up being small. Also, due to the use of querySelector in this solution, it does not support IE8. It could be rewritten to not use it, or you could use jQuery to provide that.
All that said, here is the hack: https://jsfiddle.net/esb8twwe/ The trick here is that each rectangle in the treemap is going to be an SVG 'g' element (group), with exactly one rect and exactly one text element. So we can simply iterate over all the groups in the SVG element, and filter out all the ones that don't fulfil this requirement. Then, the text content of the 'text' element is the label, and the bounding box of the 'rect' element is the rectangle. Please keep in mind that the DOM structure might change in future versions without any warning, and so your chart may break with some future release.
