Is there a tool for Django project structure/information flow visualization?

Question

I would like to be able to view the structure of my Django project, i.e. which urls point to which views, which views point to which templates, which css files are included in which templates etc.

I know about the great model visualization tool in Django command extensions, but I need a different tool that is able to visualize links between:

1. Urls and views;
2. Views and templates;
3. Templates and other templates (via {% extends %}, {% include %} and custom template tags);
4. Templates and static files (css, js, images).

Are there any?
