Re: dynamic svg

I think that creating SVG images from XML data will be very suitable in your case. 

You can include values and other data in the form of an XML documents, and prepare an XSLT stylesheet that transforms the XML document to an SVG document according to your needs. I think that this is not very difficult and will be very useful, since the same style sheet can output different images. 

In the reality, in the context of my proper work, I use the same principle to create dynamic adapted content for heterogeneous devices, and this controlled by some parameters included in an input client profile.   

You can also take a look on (transforming XML into SVG) :

I hope this will help
