KGraphViewer

What is it ?

KGraphViewer is a GraphViz dot graph viewer for KDE. The graphviz program suite is a free software set of layout engines for graphs. They are commonly used in scientific domains and particularly in computer science. But until now there was a lack of GUI to look at the graphs. Programs given with GraphViz are, I feel, out of date X11 or Tcl/Tk ones with few functionalities.

KGraphViewer is aimed at replacing these tools with a modern user-friendly GUI with all the power of a well integrated KDE application.

Download

As part of the kde extragear package, you can download the latest subversion version from the KDE subversion repository.

Stable releases are available through the KGraphViewer Home Page.

Planned features

• port to KDE4 ;
• save session data about graph (layout program used, zoom factor, etc.) ;
• integration in kate and konqueror (so a change in the kate view of the graph would relayout and reload the file) ;
• menu to open the file in kate OR to open a katepart inside the kgraphviewer window ;
• loading of big and huge graphes (currently, there is performance problems around 1000 nodes) ;
• progressive support of more and more dot attributes and values ;
• layout in background (thread to don't block the interface, with progress bar) ;
• etc. (See the TODO in the distribution for an up-to-date list).
