Visifire
Visifire is a set of data visualization components. It currently supports Charts and Gauges. Visifire is available on Microsoft Silverlight, WPF, Windows Phone, and Windows 8. One can use the same API to create charts and gauges in mobile, web, and desktop environments. Visifire can also be embedded in any webpage as a standalone Silverlight App. It is independent of the server side technology being used. Hence, Visifire can be used with ASP, ASP.NET, PHP, JSP, ColdFusion, Ruby on Rails or just simple HTML with JavaScript. Visifire also has a wizard-driven solution to create charts in SharePoint.
