The sample set includes an example that does this (SalesOnStates)

The original geographic data however, have connectivity (2d lines forming
the boundary of each state).  The boundaries are used to construct the
polygonal shapes (faces, edges, loops in DX parlance).  Properties
associated with each object are used to color and/or for the height of
vertical extrusion.

Does anyone knows how to do this highlight picture???

If possible, imagine that the data is scatered, consisting each line of a
2D Vector, an integer representing the color and a float-point to the
z-coordinate.
I've tried to use the connect module (trought triangulation), but I imagine
that I should "truncate" the values generated by that module, but I don't
know how (how to use the compute in this case, and what is the operation
for truncation (or rounding).

It's because I don't want to represent any interpolation between the
different z-index degrees- just something like what happens on the above
picture.
