A JavaScript Sparklines Library – Sparky

Sparklines, the tiny charts that can be used near a sentence, headline, graphic.., are very handy for visualizing data inside the content.

Sparky is a free JavaScript sparklines library that depends on Raphaël and very easy to use.

It has support for multiple chart types (line, bar and area) where line + area charts can have multiple colors as well.

The usage is very straightforward; just create an HTML element (preferably <span> for inline use) and provide the values as an array with a data attribute. And, define the settings (width, height, colors, padding, etc.) with a JS function.
