InfoPath Dev

I've used InfoPath to merge the data into one xml file. (not completely cleanly- but I can address that later) I opened the XML file with excel and that allows you manipulate the data- pretty cool. But, so what? Now I want to produce reports, charts, etc. Any suggestions on products that do this well?

I thoughts Charts canbe easily created by Excel, You can also Excel Services when you like to expose these charts in SharePoint

I once the data is merged, and you can link it to a database, use Reporting Services.  Within Reporting Services you can easily add Charts to the reports
