Mark, MS Office Web Components(OWC) are the way to go now a days. OWC is highly optimized for producing dynamic charts and graphs on the web and works great with VFP. We have some live examples and downloadable code for use with VFP/ASP at www.activevfp.com and Rick Strahl just did a whitepaper on it at http://www.west-wind.com/presentations/OWCCharting/OWCCharting.asp.
After struggling with automating MS-Graph exports to Gif, OWC is a great improvement, although, you can't do 3D graphs.
There are other solutions like ChartFX, but, they cost $$$ and I'm not sure how smoothly they work with web apps...
