Hi Jason,

if you want to use Graphmapper for this, you'll have to at least feed
2 value streams through 2 mappers and then combine those 2 values at
the other end into 1 value again.

But, first of all you have to decide how you want your 2D number set
to change. Is there a mathematical function that describes this
variance? You could also decide to use a Rhino nurbs surface as a 2D
graph, and intersect it with a bunch of vertical lines in a grid. The
z-value of the intersection point of each ray will then work as a 2D
graphmapper.
