How to use Graphviz/Networkx in django?

[shaw...@gmail.com]

Hi everyone,

If I have three models and I successfully displayed the data using templates and views, how can I use graphviz or networkx to draw graph using the data that I displayed?

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.

1) Don’t drive species to extinction

2) Don’t destroy a habitat that species rely on.

3) Don’t change the climate in ways that will result in the above.

Hi, thank you for your help.

But I think this link cannot really solve my problem. My question is actually how to visualize the data of my model, rather than visualize the model. 

The situation is, As you can see, the Formula detail table include the reactants that participates in the reaction, now I want to add a function to this page, like add a button at the right side. And when I click on the button, a graph could be generated automatically. The graph should looks like '10fthf5glu_m(in a circle) -> 10fthf5glu_c(in a circle)' I know this function should be done by using Graphviz and Networkx, but how?

Hi,

It's relatively simple. Just generate proper input file for graphwiz or networkx to consume call that tool for input file and create output file. Then render output file via view to your page.

Thanks a lot for your help!

But since the data that needed to be visualized is already shown in the page, generate input file is actually not necessary. In that case, what should I do to make django aware that the data shown in the page is the 'input' how can I call the tool to process the visualization?

I am sorry to ask the stupid question.....I am new to django and I am really hope you could help me!

Thanks

Hi,

You could take a look at django-extensions how it generates graphs from models as an inspiration.
