Charts For WPF and Silverlight

I have been digging around on the web lately to see what I can find that provides a solid, seamless charting ability to WPF and Silverlight.  There are a ton of choices out there.  After spending a good couple hours last night and some time today I have decided that I am going to go with Visifire.  These charts are pretty solid and ridiculously easy to implement.  Check out this video for some of the samples they have.

I hope to have some write up how to entries in the near future.  I have just completed a few work related projects and I know there are some good samples in all that which are publishable.  : )
