- The dataflow paradigm is naturally 2D or 3D, so it makes a good
- visual interface. You can have objects and messages flowing around
- the screen instead of raw data. Some dataflow paradigms have logical
- assertions flowing around; each node rewrites its input assertions
- and emits new output assertions.
-
- There are several survey books of visual programming interfaces
- out. They tend to be hodgepodges of many different kinds of
- programming.
