Graphviz Python Binding for Python 2.5 on Windows?

[Alex Li]

Hello,

I would like to use Python 2.5 on Windows with Graphviz to generate
graphs. I used yapgvb but it only requires Python 2.4 (won't work
with Python 2.5). Other packages like pydot seems to be unmaintained
or requires custom building to be used on Windows (pygraphviz), which
I tried to avoid. Any suggestions?

Thanks in advance,
Alex

Hi!

You can also use/call GraphViz by COM.
It's run OK with P2.3 - 2.4 & 2.5

Thanks Michel, I will give it a try.

Alex,
You can always pipe your dot file directly to the dot or neato
executables using the subprocess method then read the output. This way
you don't have to install yapgvb or other adapters and it will work
with Python 2.5. But you will need to compose your dot file as a giant
character buffer...

Not really a solution, but you can always install a virtual machine
with Ubuntu (or other linux flavour) where pydot is available for
python2.5 (sudo apt-get install python-pydot).

Thanks all for your suggestions.

Nick: I am trying to avoid generate the dot file manually so that I
can minimize bugs coz by me ;)

SPE: Unfortunately that may be too radical ;) I work in a corporate
environment (read: MS shop) and my group wants to generate a
dependency graph of our system. I was trying to take this opportunity
to introduce some python to the group. They were amazed when I came
up with the script in a few hours and were willing to try it out by
installing python, yapgvb, and graphviz. But it won't work on python
2.5! It's kind of a bummer to tell them to install an older version
of python.

On second look, I will try pydot again. Despite no release for a long
time, it seems to be reasonably complete. Now, I am sure we will redo
it in C# after my "prototype" ; but that will just prove the advantages
of python in terms of code size and productivity :)

try the networkx package, it includes the pygraphviz module that can
generate dot files:

should've checked it before posting, it seems nowadays is actually a
separate package

Sadly this happens often, they don't want to keep using two languages
when one may suffice. On the other hand, you may even find a way to
adapt your Python code to IronPython, so maybe you can avoid the
translation to C#.

Thanks Albert. I looked into pygraphviz as well but it requires
compiling C extension, and there is no Windows compilation instruction
(though it probably won't be hard).

You could simply generate the .dot files from python and do os.startfile
on the dot file (which is what I do because it is remarkably easy!)
