its not that clear. according to the timeline provided
at Ircam,
"Patcher", the predecessor of Max, was started in 1986. i don't know
if patcher had a visual dataflow model or not. Max itself didn't exist
till 1990.
Miller Puckette (the creator of Patcher and PD) probably could answer that
question and probably also knows something about prior art. Relevant articles
can almost certainly be found in Computer Music Journal
(

Prodeedings of the ICMC (
