How can I draw diagrams from database in python
Question: How can I visually model items in a database using python?

I have a [Django](https://www.djangoproject.com/) project that currently
models my home network in the admin views. It currently describes what devices
there are and what they are connected to. For example:

    
    
    Devices:
        Computer1
        Computer2
        Laptop1
        Mobile1
        Router1
        ROuter2
    
    ConnectionTypes:
        Wireless24ghz
        Wireless5ghz
        cat5
        cat5e
        cat6
    
    Connections:
        host1:
            src:Computer1
            dst:Router1
            con_type:cat5e
        trunk1:
            src:Router1
            dst:Router2
            con_type:cat6
        host2:
            src:Mobile1
            dst:Router1
            con_type:Wireless24ghz
    

The database is a bit more complex than this, however I'm keeping it simple
for now as it's not that important.

What I am wondering is, how I can graphically model my network using python
code to look at the database tables? By graphically model I mean something
similar to a Visio diagram in that I can see it and (not necessary but a HUGE
bonus) interact with it, either via webpage or application.

Are there any existing python libraries that provide this sort of
functionality? I understand JavaScript is good for this kind of modelling but
I'm completely unsure of how I would go about doing it.

It's worth noting I'm not after anything fancy, simply drawing devices as
rectangles and connections as lines going between rectangles is good enough.


Answer: I am pretty sure there is no ready solution for this. Look at the graphviz
library and make a management command to create a DOT graph. Here is a
graphviz tutorial article <http://matthiaseisen.com/articles/graphviz/>
