HyperFlow: an integrated visual query and dataflow language for end-user information analysis

We present HyperFlow, a novel visual language for information analysis that combines features from visual dataflow and visual query languages into a unified framework. HyperFlow is designed to make it easier for users to retrieve, filter, and manipulate information, using databases alongside e.g. Web services, in a transparent, intuitive, reproducible and traceable manner. It allows users to visually design and execute information analysis processes in a single diagram. We present HyperFlow's constructs and describe the characteristics of a prototype interface we have implemented.
