Best Way to Create Dynamic Reports

We have an online software tool where people do assessments and we produce reports for them by pulling the data they inputted, doing calculations on it, producing graphs, etc. I created the graphs using CSS.

Up till now I've generally PDF'd the reports manually and sent them to clients because they really only display and page break reliably in IE. I can't even set up page breaks because I use absolute positioning to get a couple of graph components to overlap, and absolute positioning is incompatible with setting page breaks.

We are trying to get the software more independent of our having to manage the details like printing off reports for clients because we want to drop the price.

I'm trying to determine whether to use dynamic PDFs (and what is the best tool for that), whether to stick with CSS and find a way to break the pages appropriately, or whether there is a better solution.

FYI, our software uses Perl and MySQL.

A bit of background on me... I'm not a programmer by training and cut my teeth on modifying this software, but I've been working at it for several years now.

Thanks so much for any help!
