We are looking for a rich dashboard component.
Ideally, we do not want to use Flash technology but instead something implemented with pure AJAX. While YUI offers an excellent AJAX library and it offers a lot of rich UI components it does lack, to my knowledge, sophisticated widgets like dashboards. For sure, such components can be found out of the box of XCelcius or Flex.
Is there a decent open-source dashboard component that is perhaps built on YUI framework?
