Web apps using django and integration of other frameworks

I am building a web application(a dynamic site) using Django framework. I will require to add some real-time features such as chatting , video conferencing , online whiteboard collaboration etc. I know Django is not that great when it comes to real-time apps. So I would like to ask is there a way where I can integrate other services into Django to build real-time app say chat app . for example can I use Node.js with Django or any other technology.

Also I would need to visualise data in my site so what is the best way to do that?
