The graph2svg stylesheets can be rewritten for XSLT 1.0. I have tested 
this with my XForms implementation: the XSLT 1.0 stylesheet is applied 
locally by the browser to an XML instance.

Converting from XSLT 2.0 to XSLT 1.0 is not quite easy because of XPath 
2.0 expressions, XPath 2.0 definitions of functions, math library to be 
implemented with iterative algorithms,...

Have a look at
