Vy is the best rate of climb for an aircraft. I can't seem to
visualize why Vx is not the best rate of climb.

Simple: The steeper you climb, the slower the airplane flyes (as long as
you don't have excessive power).

So you can climb steep but flying slow, or you can climb shallow but
flying fast. Simple calculation shows that you can optimize for shortest
distance or shortest time, but those optima need not be the same (and
usually are not).
