Sparky

Sparklines are intense, simple, word-Sized Graphics. Sparky is a javascript library for drawing them dynamically in your web browser. In the words of Edward Tufte, who coined the term:

Sparklines mean that graphics are no longer cartoonish special occasions with captions and boxes, but rather a sparkline graphic can be everywhere a word or number can be: embedded in a sentence, table, headline, map, spreadsheet, graphic.

You can read more about sparklines and their into uses on Wikipedia, Tufte's site, or in his book,Beautiful evidence.

Featureswhat it do

Sparky supports line, bar, and area charts. line and area charts can include variably colored and sized dots. both dot and bar colors can be defined either as a single value for the entire data set, or as functions to be evaluated once per data point.

Sparky can also render larger time series graphics:
