Microsoft Visual Programming Language (VPL) is an application development environment designed on a graphical dataflow-based programming model.

A VPL dataflow consists of a connected sequence of activities represented as blocks with inputs and outputs that can be connected to other activity blocks. Activities can represent dataflow control or processing functions, pre-built DSS services or your own defined activities you create in VPL. The connections between activities pass data as messages. The resulting application is therefore often referred to as dataflow orchestration, the coordination of information between a connected set of processes.

VPL is targeted for beginner programmers with a basic understanding of concepts like variables and logic. However, VPL is not limited to novices. The programming language may appeal to more advanced programmers for rapid prototyping or code development. As a result, VPL may appeal to a wide audience of users including students, enthusiasts/hobbyists, as well as possibly web developers and professional programmers.
