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 a modern GUI to look at the graphs.

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

Download

You can download the latest development version version from its KDE git repository.
