1So you have other constraints? Is this a public web site or is it an intranet? Are you only interested in something which can be acheived with with free/open source products or would you look at a commercial product?AnthonyWJones– AnthonyWJones2009-09-01 08:22:11 +00:00Commented Sep 1, 2009 at 8:22

You could check out Google Charts.

There are a number of great javascript libraries which can take datasets and convert them into graphs.
are two of the big ones. The plus of javascript is that the processing is done client side and you don't have to send over images, just JSON.

Dojo also works well, though documentation is a little scarce.
Microsoft's Office Web components (OWC11) also works on the server side, and it's fairly easy to use.
Third option is to use plain old HTML. Works well sometimes if you want a simple chart, like a horizontal bar chart. You can use a table, with div / span tags set to correct widths ad colors for the bars. Free, easy and requires no plugins of any kind to work.
