Provide an option to disable bounce effect in graph panel

[Mister-Hope]

I greatly dislike the bounce effect in graph panel, and I think that's not my own taste.

There are some people which can feel dizzy when watching complicated animations, and I am one of them. Not kidding, I feel very bad every time I try to enter the graph panel, that's also why CSS standard have a Prefers-reduced-motion media in a11y part.

We can respect the Prefers-reduced-motion, together with a higher priority option to control the animation behavior, for better a11y :)

Maybe the same as issue #567?
