Are you suggesting 'Gnumeric provides the SVG, Inkscape draws it'?
I wasn't so much think about 'Gnumeric provides...'
I was thinking/hoping that the because the graphing functionality of Inkscape has been seperated out into a library and that inkscape could reuse that only that part of Gnumeric and do so relatively easily without the need to do things by embedding.
However I haven't given much thought as to how an interface to the graphing functionality could be constructed. One of the ways would be to embed Gnumeric using Bonobo but I hope that there is some other more generic portable way.
Not sure I'm explaining it very well but unless a developer is interested there is not point in my talking about it. I should probably just file an RFE and hope it gets included in the long term plans.
