Hello,
(Google mails keyboard shortcuts are way too efficient!! Sent the first one
by mistake!)
Have a look at the net.sf.taverna.t2.ui-

}
You could then view the SVG document straight in the browser (in theory -
your browser experience may differ!).
You will have to create the workflow in the first place which could cause
some issues with Raven although if you already have the worklfow then you
just have to use the code above to create the SVG document. The false and
null in the SVGGraphController are for setting it to interactive (a
workbench only setting) and the svg canvas to render the graph on (you may
or may need this for your usage).
David Withers is the real expert on this stuff and can hopefully correct any
mistakes I've made here.
Cheers,
Ian
