Server Side Requirements: None. FusionCharts runs on Windows, Mac, Linux, Unix or any other server. Just make sure that your server's MIME is configured for SWF files to ensure proper streaming. Most servers come pre-configured for SWF files.

Client Side Requirements for Rendering Flash Charts: Adobe Flash Player 8 (or above). Adobe Flash Player is a free and light-weight plugin to render Flash movies. It can be downloaded from www.adobe.com. It's one of the most widely installed plugin on this planet. For client-side-export, Flash Player 10 is required.

Client Side Requirements for Rendering JavaScript based Charts: FusionCharts automatically renders JavaScript based charts on those computers which do not have a Flash player installed in them. The only client side requirement is a modern browser (including those on iPhone/iPad) which supports JavaScript. For example, support is provided for Internet Explorer 6 and beyond.
