Indeed. Google for the programming language "Prograph", developed
in the early 1980's at McGill University, IIRC, and continued at
Dalhousie University by Tomasz Pietrzykowski, Michael Levin, and
others. [Hmmm.... <http://users.cs.dal.ca/~smedley/Research.html>
indicates that work in that field is still going on at Dalhousie.]
It was an almost fully functional, graphical, dataflow language
which one programmed by "wiring" sources, sinks, databases, and
processing boxes together, very much like drawing a schematic.

Tha abstract at <http://portal.acm.org/citation.cfm?id=317169> has
additional description, wherein it is compared to Lisp & Prolog:
...[but] which overcomes some of the shortcomings of Lisp by
replacing the usual textual representation of programs by
pictures called "prographs".
