Abstract: We present a new visual programming language and environment that
        serves as a form of feedback and representation in a Programming by
        monstration (PBD) system.  The language differs from existing visual
        languages because it explicitly represents data objects and implicitly
        represents operations by changes in data objects.  To improve feedback
        and provide a closer union between the PBD system and the program
        representation, the visual language is integrated into other parts of
        the system, such as the editor. Finally, in order to enable new
        operations to be added easily to the system, we introduce a
        declarative language for specifying how an operation's visual
        representation is generated.
