Charting is one area that we've wanted to see improve in Office Live.  Fortunately, since enough of our platform is opened up, developers can take it upon themselves to do some charting work if they need it for their customers.

 Darren Johnstone has a blog that covers the work he is doing with Office Live.  He's one of our early partners in the UK.  He recently posted several code samples for how to extract data from an Office Live Business App or Workspace and turn it into an SWF flash chart.  This is a nice innovation on the Office Live platform.  Check it out! He even packaged everything up as a download so you can try it out for yourself on your own Office Live site.  This is NOT to be missed!
