On Order-preserving, Gap-avoiding Rectangle Packing

Software maps provide a general-purpose interactive user interface and information display in software analytics. This paper classifies software maps as a containment-based treemap embedded into a 3D attribute space and introduces respective terminology. It provides a comprehensive overview of advanced visual metaphors and techniques, each suitable for interactive visual analytics tasks. The metaphors and techniques are briefly described, located within a visualization pipeline model, and considered within a software map design space. The general expressiveness and applicability of visual variables are detailed and discussed. Consequent applications and use cases for different software system data and software engineering data are discussed, arguing for the versatile use of software maps in visual software analytics.

We introduce a systematic approach for automatically creating a visual diagram, akin to the graphical SCADE model, from a Lustre program. This not only saves tedious manual drawing effort but also enables modeling software to automatically provide the developer with different meaningful views for the same program. We also extend the SCCharts language with data-flow constructs that adhere to the Lustre semantics, which permits a translation from Lustre to graphical SCCharts. This allows using the SCCharts code generation, simulation and visualization tooling also for Lustre programs, in addition to the already existing Lustre compilation techniques. Furthermore, we investigate how the sequentially constructive model of computation, used in SCCharts and other synchronous languages, can be used to conservatively extend Lustre. We have implemented and validated this work with the Eclipse-based open-source KIELER framework.
