Ugdymo

UGDYMO is a modular, open-source framework for creating, simulating, and visualizing dynamic models and graphs. It provides a core time-stepping engine, a graph data model, and an interactive rendering layer suitable for web and desktop use. The system emphasizes extensibility through plugins and scripting, enabling researchers, educators, and developers to build customized simulations with minimal boilerplate.

At its core, ugdymo separates computation, data, and presentation. The kernel handles time advancement and events; the graph model stores nodes and edges with attributes; and the rendering layer provides interactive layouts via hardware acceleration. A plugin API adds new node types and layouts, while Python or JavaScript bindings support prototyping and automation.

UGDYMO originated as an international collaboration in the 2010s and released its first stable version in 2014. Subsequent updates expanded scripting, collaboration features, and scalability for larger graphs. The project remains community-governed, with contributions from universities, research labs, and independent developers.

Common applications include education laboratories for systems dynamics and network analysis, epidemiology modeling, and demonstrations of complex systems. The platform ships with example models and visualization templates, and users can share reproducible notebooks and plugins through a central catalog.

Reception has noted ugdymo's modular architecture and visualization strengths, while pointing to a learning curve for newcomers and possible performance limits for very large simulations. Its open-source license and cross-platform support have aided adoption in academia, data science, and education.
