Render graphs as SVG instead of PNG
1. awesome crispness on Retina displays (currently it’s meh)
2. can be rendered much faster (less server load + better redraw times)
Cons: IE 8 doesn’t support SVG. A possible workaround is using something like Raphaël (a JS library for cross-browser vector graphics), but even a checkbox in the settings "I swear I’m never going to use IE 8, now please give me my SVG already!" would be cool.
