I'd look at it this way...

First, is a graph of the slope of at every point. Pick some points in the x-y plane and draw a little line segment with the slope from at that same x. Connect them, and you've got , almost. The caveat is when you integrate , you'll get a constant of integration, and thus an infinite number of possible 's to plot. To get the specific graph of your , you need to know a specific point that satisfies your particular .
