Anyone know of any good animated graph controls?

As the title says, anyone know of any good ANIMATED graph controls?

Example, I pre program all of the data then when it loads It 'animates'. I've seen alot of them do this in Flash, and WPF. However, I havn't used Flash in many years, and never understood WPF.

Any (paid, or free) controls would be great.

Thanks for the reference in advance.

What do you mean by the term "animated graph"? A graph that changes with time (such as the cpu usage graph in window's task manager)?
