Shoudl I generate reports client or server side?

I am thinking of a standard AJAX setup (JS<->PHP<->MySql).

I want to generate reports (charts, tables, etc) probably using at maximum a few dozen data points (certainly never over 1k).

I am unsure whether to D/L all data on initial page load and generate charts when the user changes a parameter - say start date for example - using JS totally on the client side or to send an AJX request to the server & use PHP there to generate & return a chart.

What should I take into consideration?

• Is there a standard approach, or does it "depend"?


• Any considerations of performance with so little data? Security?


• Might client side be better if I want to export the reports?


• Does it just boil down to which ever free charting package looks good to me?
