[vtkusers] scatterplot with different marker shapes, sizes and colors?

[Cory Quammen]

Mario,

I am not aware of any capability in VTK to change the marker points or
shapes based on the input data. A patch would be required to support
that. It might be too hard to implement if you want to give it a try.

Best,
Cory
