Multiple-Representation Visual Compositional Dataflow Programming
Many tasks that end users want to accomplish with a computer program
are fundamentally data-flow transformations, and both visual and textual
programming systems have been created to fill this need,
but these are often inflexible, unapproachable, or cumbersome, satisfying
a niche at one stage of the process but limited at others.
An approach that suits one part of the program, or one time in its
development, may be confounding at another, but the user is stuck with
both the constructive and obstructive aspects of a tool’s chosen paradigm
Much of this difficulty can be removed by enabling the cohabitation
of multiple editing paradigms in a single program for the user to choose
how to tackle the current point in the process - and change their mind.
We present a new data-flow programming environment where the
same program, or parts of the same program, can be viewed and edited
as linear text, a node-and-wire graph representation, or a
two-dimensional grid layout, and the correspondence between these
representations is made clear through a continuous visual identity
for each part of the program.
