Charting in web-based applications

Question

What are the various charting tools that are available for displaying charts on a web page using ASP.NET?

I know about commercial tools such as Dundas and Infragistics.

I could have "googled" this but I want to know the various tools that SO participants have used? Any free charting tools that are available are also welcome to be mentioned.

If you do not mind using Flash to display your graphs, Open Flash Charts supports a lot of languages. This was also the choice used for the Stackoverflow reputation tracker piece as mentioned in this question
