Free .NET Web Charting Control
Ah, the simple joy of getting something for nothing.
As part of the Chamber Project, we went hunting for a charting component for .NET. We ended up discovering the WebChart Control.
The WebChart Control is a free charting component for ASP.NET. It does line charts, column charts, area charts, scattered charts, stacked column charts, pie charts, all kinds of charts. You can bind it to a dataset or you can set values manually. You can enhance the look of the chart with shadows and other effects.
The site itself has the component to download and tons of samples. Feel free to use it in your ASP.NET apps.
