Reactive graphs in action (extended version)

TL;DR

This paper introduces Marge, a web-based visualization tool for reactive graphs that animates their operational semantics and aids in analyzing adaptive and featured transition systems.

Contribution

It presents Marge, a novel tool that visualizes and animates reactive graphs, bridging the gap between theory and practical analysis of concrete systems.

Findings

Marge effectively visualizes reactive graphs with labels.

The tool animates the operational semantics of reactive graphs.

It demonstrates applicability to adaptive and featured transition systems.

Abstract

Reactive graphs are transition structures whereas edges become active and inactive during its evolution, that were introduced by Dov Gabbay from a mathematical's perspective. This paper presents Marge (https://fm-dcc.github.io/MARGe), a web-based tool to visualise and analyse reactive graphs enriched with labels. Marge animates the operational semantics of reactive graphs and offers different graphical views to provide insights over concrete systems. We motivate the applicability of reactive graphs for adaptive systems and for featured transition systems, using Marge to tighten the gap between the existing theoretical models and their usage to analyse concrete systems.
