Just in case I'm allowed to use Highcharts, could you make your
conversion code generic enough so I could use it too? :)
And just for your information, the current SVG converter of highcharts
uses following post variables to a php file that calls a java tool
(source is available btw):

 * $tempName string The desired filename without extension
 * $type string The MIME type for export.
 * $width int The pixel width of the exported raster image. The height
is calculated.
 * $svg string The SVG source code to convert.
