This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript.

[2 cents] This is pretty cool and might work nicely for creating a mini version of something you create a larger version of using jQuery FLOT. I know this one's been around for a while, but I'm still waiting for a prime use case so I can tinker with it. (usually when I say something like that I end up finding a reason to use it within a day... ha ha).
