title: radar chart / spider chart xsl-fo svg?
body: <p>I have to generate a pdf document written in xsl-fo. I have 8 categories where I pull the percentage into the xsl-fo document, and I need to visualize it on a radar chart.
  Is it possible to create a spider chart in xsl-fo? 
  Maybe in svg and inserting it as an instream-foreign-object?
