This plug-in provides a binding of Open Graph Drawing Framework to QtQML (Version 5.0+).

The Open Graph Drawing Framework offers sophisticated algorithms and data structures for the automatic layout of diagrams. Some parts of OGDF are experimental and unstable, so don't expect all algorithms to work equally well.


  • A wide range of layout algorithms such as
    • Orthogonal and polyline layouts
    • Multilevel layouts
    • Energy-based layouts
    • Upward layouts
    • Planar layouts
    • Tree layouts
    • etc.
  • Various generators for
    • Random graphs
    • Random trees
    • Random hierarchies
    • etc.
  • Easy to use - it's QML after all


You need to have a C++ compiler, Qt 5.0+ and CMake 2.8.11+ installed.

There are many ways to use CMake, but this is the easiest one: start Qt Creator, open CMakeLists.txt as new project, follow the instructions, hit build and you're done.

Quick Start

Once build, you can start ogdf-demo to find out what algorithms are available and how you want to use them to solve your problem.

To use the plug-in in your own project, you need to compile an OGDF directory and copy it to your application's working directory as follows:

OGDF/                 -- plug-in directory
  libogdfplugin.so    -- compiled plug-in (Linux only)
  libogdfplugin.dylib -- compiled plug-in (OS X only)
  ogdfplugin.dll      -- compiled plug-in (Windows only)
  qmldir              -- module definition file
