Caching?

Is there a way to make this cachable? currently the browser (firefox/chrome) at least, seem to do a fetch for every sparkline. Tried changing the code to use location.hash, but it still does it.

There should be a way to CDN specific lines at least – I'm using Github to host this, and I suspect I'm not pointing at the CDN'd Github pages IP. That would cache specific URLs, but I'm not sure how to cache the svg files themselves.

One way might be to provide SVG placeholders with data attributes:

<embed
  src="//sparksvg.me/line.svg"
  data-points="0,4,7,10,8,12,9,7,3,0"></embed>

That's very off the top of my head – could it work?

Yes, I think that would work from the caching side at least.

Cool. I seem to recall there was an issue getting data on the embed element from inside the SVG, but don't remember specifics. Fancy pull requesting?
