xdot.py can be used either as a standalone application from command line, or as a library embedded in your Python application.
xdot.py script became much more popular than I ever anticipated, and there are several interested in improving it further. However, for several years now, xdot.py already meets my own needs, and unfortunately I don't have much time for maintaining it myself.
So I'm looking into transition xdot.py maintenance to others: either hand over the maintenance xdot.py to a community or indicate an official fork of xdot.py.
- Since it doesn't use bitmaps it is fast and has a small memory footprint.
- Arbitrary zoom.
- Keyboard/mouse navigation.
- Supports events on the nodes with URLs.
- Animated jumping between nodes.
- Highlights node/edge under mouse.
Not all xdot attributes are supported or correctly rendered yet. It works well for my applications but YMMV.
Text doesn't scale properly to large sizes if font hinting is enabled. I haven't found a reliable way to disable font hinting during rendering yet.
Download and install:
apt-get install gir1.2-gtk-3.0 python3-gi python3-gi-cairo graphviz
If you install xdot.py from PyPI or from your Linux distribution package managing system, you should have the
xdot somewhere in your
When running xdot.py from its source tree, you can run it by first setting
PYTHONPATH environment variable to the full path of xdot.py's source tree, then running:
python3 -m xdot
You can also pass the following options:
Usage: xdot.py [file] Options: -h, --help show this help message and exit -f FILTER, --filter=FILTER graphviz filter: dot, neato, twopi, circo, or fdp [default: dot] -n, --no-filter assume input is already filtered into xdot format (use e.g. dot -Txdot) -g GEOMETRY default window size in form WxH Shortcuts: Up, Down, Left, Right scroll PageUp, +, = zoom in PageDown, - zoom out R reload dot file F find Q quit P print Escape halt animation Ctrl-drag zoom in/out Shift-drag zooms an area
If no input file is given then it will read the dot graph from the standard input.

ZGRViewer -- another superb graphviz/dot viewer
dot2tex -- python script to convert xdot output from Graphviz to a series of PSTricks or PGF/TikZ commands.
The PyPy project also includes an interactive dot viewer based on graphviz's plain format and the pygame library.
