Please suggest a free Web Chart tool for asp.net(VS 2003).

I need a free web chart for my website which is developed in Visual Studio 2003. Currently, my website is using WebChart tool but it is not compatible with the latest browsers(e.g. Chrome ).
I've tried Zed Graph tool but it is working in winforms not in Webforms.
Please suggest me free web chart tool for my web application that should work in VS2003 & .NET Framework 1.1 and also compatible with the latest browsers.

Thanks in Advance.
