Architecture and applications of the Hy+ visualization system

The Hy
⁺
system is a generic visualization tool that supports a novel visual query language called GraphLog. In Hy
⁺
, visualizations are based on a graphical formalism that allows comprehensible representations of databases, queries, and query answers to be interactively manipulated. This paper describes the design, architecture, and features of Hy
⁺
with a number of applications in software engineering and network management.
