The site is currently javascript only, the server is only serving static files, and the svg tags are generated in the browser using Raphael.js.
That said, I have already been pondering about this for a previous projects: http://populationpyramid.net and there are solutions : either export the svg tags through an ajax query to a server that would then render it as PNG, or create a script that would create the svg files directly from the data. I did not take time to implement this, though (I have to sleep sometimes...)
