yGraph Editor

The application lets users create, import, edit, and automatically arrange a wide range of diagram types, including flowcharts, UML class diagrams, BPMN, semantic networks, family trees, and social network visualizations. An intuitive graphical interface supports manual drawing as well as automatic layout algorithms that organize elements without manual positioning. Users can import data from Excel spreadsheets or XML files, and export the results as bitmap or vector graphics in formats such as PNG, JPG, SVG, PDF, or SWF.

It runs as a Java‑based desktop program on Windows, macOS, and Linux, requiring only a suitable Java Runtime Environment. The software is built on the yFiles diagramming library, which provides the layout and analysis capabilities, and incorporates UI components from JIDE Software for a consistent look and feel.

The tool is offered free of charge for both personal and commercial use under the yEd Software License Agreement, though redistribution or automated processing is prohibited. Its cross‑platform availability and support for many diagram standards make it suitable for developers, analysts, and anyone needing to visualize structured data.
