[Interest] QML Custom Scene Graph animation?

I'm playing with custom QML components in Scene Graph. The kind of
component that i want to make is a system monitor like component (and
learning Scene Graph while doing that is a big plus). Now i'm a bit
stuck in the animation area. I can - obviously - just draw a line in
some custom component and then move that component in either x or y
(or both) which will give the same results, but that's not what i'm
looking for.

What i'm looking for is the paintEvent alternative for Scene Graph. I
have "updatePaintNode" re-implemented and am drawing stuff in a
component, but how can i update it when the next frame is requested? I
don't know if i should use a timer, do i? Doesn't Scene Graph work
with vsync and shouldn't i be doing something with that? If so, how?

I kinda miss an example about making an animated component with Scene
Graph. Or if someone knows of one, please do link me to that.
