One of the common difficulties in a graph based visual language is to develop its executable semantics and achieved its execution in a distributed environment. In order to address some of these issues, this paper outlines the general control flow semantics of a graph based visual language. In doing so, this paper also discusses a sound technique implementing such semantics permitting execution in a distributed environment. An implementation is sketched for a domain specific graph based visual language, called VRPML.
