The Open Graph Drawing Framework (OGDF) is an open-source C++ library offering data-structures and algorithms specifically tuned for, but not restricted to, graph drawing applications. It is not a program which can be directly used to draw graphs (see Gryphon for such an application), but an algorithmic layer to be used within such other programs.
OGDF compiles under Linux, MacOS and Windows, with current GCC and Microsoft compilers. The library itself is self-contained, i.e., it does not require any other libraries such as Leda. Optionally, OGDF can be compiled against Osi Coin to enable additional algorithms which require an (I)LP solver.
We do not follow a regular schedule, and new release will come whenever we feel that OGDF has changed or grown enough to qualify for a new release. When bugs pop up, we will publish hotfixes for the current release.
Each release version has a codename and a version number YYYY.MM, whereby YYYY gives the year and MM the month of the release date. Subsequent bugfixes of a release are denoted by a single letter (increasingly) appended to the release’s version number.
