Data Visualization Components now part of SDK
Just saw this post by one of the Flex engineers, Deepa, that the upcoming Flex 4 SDK will now contain the Data Visualization Components. These components include the AdvancedDataGrid, OLAPDataGrid and all the Charting components. This means you no longer need a serial number to use these components within any Flex projects build with version 4 of the Flex SDK. This is a great way for Adobe to continue promoting Flex and allowing developers to create even better applications without having to spend a penny. You can download the latest beta version of the Flex 4 SDK here (the nightly builds contain the Data Visualization Components).
