Added graphs for each individual asset on the homepage!

	This took a good while but now all is working. At least I learned that tooltips are not what
	I should have been using, though instead I am now using graphs for each asset, which is far
	better than was planned. This created a horrific mess of JS code for the homepage, so I set
	up a milestone in an effort to do general cleaning of my project.
