Treemap with Tooltip

This is a treemap of the New Mexico State Budget.


The treemap itself features discriptive tooltips as well as advanced label placement such that labels only appear where they will fit. This impoves visually the treemap as well as fufilling the role of a treemap, to display relitive sizes. A treemap uses area to convey value, something that humans are inherently poor at doing. Thus a treemap is best suited when the individual details are not of the highest priority; after all, someone can read the proposed budget if they were truley concerned on the details.
Another interesting feature of this treemap is the color coded labels included below. While this would fit perfectly fine adjacent to the chart, and looks better too, not everyone has that wide a monitor and the website I develop at work does not allow for page content wider than 1040px without the side bar navigation. I prefer the look of the treemap wider with more area as the small rectangles are easier to hover over, but it is all personal preference after all.
Currently, as you may notice, if one hovers over the stroke of each div element, a tooltip with nothing inside will display. Surely this can be delt with, I just have not figued out how yet.
Feel free to use the code, if you need any help, feel free to contact me, I'd be happy to assist.
