GraphViz dot graph viewer for KDE 4 debug files
KGraphViewer is a GraphViz dot graph viewer for KDE 4. 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 a GUI to look at the graphs. Programs provided with GraphViz are: I feel, out of date X11, or Tcl/Tk applications with few Functionalities. KGraphViewer is aimed at replacing these tools with a modern user-friendly GUI will all the power of a well integrated KDE application.
