As you may know Adobe has released on its open-source web site the first nightly builds of Flex 4 aka Gumbo release. You can download them here. If you want to give it a try, go ahead, but carefully read the instructions and be cautious as these are very early builds.

The objective of this post is to see how your AIR (or Flex) data visualization application can read a Microsoft Excel spreadsheet and display its result.
