Infovis rGraph on demand nodes

I am using jit infovis javascript component (thejit.org). I have millions of nodes of data and need the rGraph to load on demand/ lazy load data or else it will never render. I can't find any doc on 开发者_StackOverflow社区it. Does anyone know if it supports on demand loading and if so how to do it?

Many thanks

I got an answer from the InfoVis forum. Here is the link to where it is done in a demo. All I need to do is work it out from the source.

Here I found the explanation of the demo, with client and server code:
