Looks like the graph SDK suits all my needs, except that graphs end up looking quite aliased. Adding an enormous data points doesn't seem to be helping as it still ends up looking very aliased. One can see it even in the 'GettingStarted' sample.
Any tips for getting smoother looking curves? If not, please consider this as a feature request. I don't think I can ship without it - my competition is displaying smoother looking graphs.
Impressive SDK though!
