UML/Dot

•    Java

---

This project cannot be used with source gt; Java version 1.4 without a major upgrade. Some part may be usable, like the diagram generation using GraphViz but you will have to rewrite parts of that as well. This program makes UML class diagrams from JAVA source or bytecode. The diagrams are generated using GraphViz Dot. The user has full control over the process and can hide or show any of the extracted elements. Requirements: JAVA v1.4 or better, GraphViz.

UMLGraph - Automated Drawing of UML Diagrams

•    Java

---

UMLGraph allows the declarative specification and drawing of UML class and sequence diagrams. The current features are part of an ongoing effort aiming to provide support for all types UML diagrams. Running the UmlGraph doclet on the specification will generate a Graphviz diagram specification that can be automatically processed to create Postscript, GIF, SVG, JPEG, fig, or Framemaker drawings.

Hello, this is JDL-Studio, an online tool for drawing UML diagrams for JHipster based on the JDL syntax. It tries to keep its syntax visually as close as possible to the generated UML diagram without resorting to ASCII drawings. The JDL-Studio web application is a simple editor with a live preview. It is purely client side and changes are saved to the browser's localStorage, so your diagram should be here the next time, (but no guarantees).

Dia - Visio alternative

•    GTK+

---

Dia is inspired by the commercial Windows program Visio, though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.
