Using FusionCharts v3.8, a new feature has been introduced which is client side exporting of charts without any internet connection.

This allows the user to export a chart directly from the browser, thus eliminating the turnaround time of sending chart data to the FusionCharts export server and wait for the converted data to be received.

To use this feature user needs to have modern browsers that support Canvas, BLOB (Binary Large OBject, or large Binary data as a single entity)  and base-64 encoding and decoding. 

These technologies are used to perform the necessary conversion from SVG to required image formats(.jpg and .png) and PDF.

Setting the attribute  "exportatclientside":"1", in the chart element of the JSON/XML data will enable the feature.
