Graph drawing and analysis library and its domain-specific language for graphs' layout specifications

Abstract

© 2018 Renata Vaderna et al. This paper presents a graph drawing and analysis library written in Java called GRAD and its domain-specific language for simplifying the process of laying out graphs. One of GRAD's main goals is to provide completely automated ways of selecting and configuring a drawing algorithm, based either on the properties of a graph or on a user's input conforming to the domain-specific language. In order to verify the quality of GRAD's main features a user study was conducted. The participants were asked to grade diagrams visualized and laid out using different modeling tools, including one relying on GRAD, which received the best overall scores.
