Graphviz (Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts.
DOT files are text files with .dot extension. They use a graph description language named DOT language. These files can be processed by some tools like dot to generate a graphical view.
Under Ubuntu and Debian, you get a set of command line tools but no GUI (Graphical User Interface) for Gnome Shell.
If you want to have a complete desktop integration for your graphviz DOT files, you need to add a proper thumbnailer and a previewer.
This article explains how to setup a complete desktop integration for Graphviz .dot files with Gnome Shell. You'll then be able to :
- see your graphviz .dot files thumbnails inside Nautilus
- see your graphviz .dot file preview straight from Eye of Gnome
This has been tested on Ubuntu Gnome 14.04 LTS Amd64 and LUbuntu 14.04 LTS. It should work on many Linux distribution with little adjustment.
