[vtkusers] Recommended way to create a 2D scatter plot

[Ben Medina]

A couple features are critical:
- Ability to color scatter points based on the values from another array.
- Ability to size scatter points based on the values from another array.

Is this possible (or planned) in the VTK Charts API?

Thanks,
Ben
