I'll try and find some time to fix this - the code removes something like an XML DocString (I'll need to get home and run this example to find the exact string it removes).

Really appreciate it. In the "Evil hack alert" there is something which doesn't render out to the reader's browser in this line: "django doesn’t like having in the middle" Can you patch that up? I'm assuming it is a control character, probably a line end, but for the sake of the reader it would be nice not to have to guess. Cheers! Hi Stu,

SVGSurface can take a file like object instead of a filename, so we use the response. Rendering happens on the SVGSurfaces Context. When .finish() is called on SVGSurface, it does it's rendering (in this case SVG data, to the response). Almost that, but not quite –

How does this work? Thanks response = HttpResponse(mimetype=’image/svg xml’)

SVG seems to get more attention these days, even from Microsoft. It's great for producing high quality and detailed graphics at large sizes. A nice paper I found on SVG vs Canvas http://www.svgopen.org/2009/papers/54-SVG_vs_Canvas_on_Trivial_Drawing_Application/ Thanks for your feature request.

I had a look at the generated SVG and it could definitely be nicer (theres no way to name particular bits). You might be able to generate a piece of SVG with cairo, then put the XML into some DOM library where you could add a css ID or Path to it. Really we need a new bit of the cairo-svg api that will let us output metadata as we go. Post here if you do anything though as I think there should be more Cairo and SVG on the web.

Any thoughts on how to hook this up for interactivity with ecmascript? Wow, you beat me, I was working on a quite similar setup past week, but had to back off due to other tasks.
