There are quite a few third party controls that'll do this for you, but I'd suggest you take a serious look at SQL Reporting Services, if you're using SQL Server. I've had to look at this several times and Reporting Services gave me all the features I needed to get graphs and charts created and published in a very short amount of time. Reporting Services is very easy to work with, but you should find a few tutorials online, if you're interested.

If you're considering going with a charting component, take a look at the Charting Component Control Gallery.

Just to follow up on this, there's a ReportViewer control that comes with .NET 2.0. I don't know if the Express editions of Visual Studio support design-time features, but it's worth a look-see; especially, if you're only looking for charting capabilities.
