I have a visualization generated by d3 (a javascript visualization library similar to Protovis or Raphael, which draws stuff using SVG elements). The vis is interactive, so the user can interact with and edit it. Once the user is satisfied with his/her visualization, I would like the user to be able to export this visualization as a PDF. I’ve tried several HTML to PDF libraries and they don’t work with SVG elements.
It is okay if the solution is either client side or server side. I’m using PHP server side but Python or Java implementations might also work.
Browser support: Ideally it would support all modern browsers, but minimally I’d like to support latest versions of both Firefox and webkit browsers.
I do not know of any strong PDF libraries on the client side.
A quick possible way would be to send the svg content to a server, and use something like batik for java to turn the svg to pdf and then send the response to the client again.
Here is a related SO for the converstion.
