I’m not sure how to creat a jQuery slider that can show in it’s slider-track a Yearly Timeline and have it auto-play with the current year shown in the handle as well?

In the left side panel there is a “Natural Forest Cover” section which is what I’m trying to achieve.
Here’s a screenshot of the JavaScript timeline shown in blue.

However my jsFiddle above is done using jQuery and jQuery UI since a Slider plugin with it’s own CSS is used.
