interested in. We do not have any tests written in Tcl for the charts, but
they are wrapped and should work. They Python tests should give a
reasonable guide on how the same might be done, and this would give you 2D
charts and a scene that you could build things on.

The underlying 2D API is not wrapped in a way that it can be easily used
from any of the wrapped layers as far as I know - i.e. I don't think you
can derive from vtkContextItem and implement the Paint method using calls
to render 2D geometry etc.
