The diagrams framework provides an embedded domain-specific language (EDSL) for declarative drawing.

This is the diagrams wiki, for collecting tips and tricks, examples, information about related projects, and any other related information. If you are looking for more structured documentation (tutorial, user manual, API reference), see the diagrams web page. There are also bug trackers for different parts of the project.

  • 0.7 to 1.0 migration: Description of API changes that may affect diagrams 0.7 code, with explanations of how to migrate to 1.0
