d3.js

[If your brain can digest this:][link]

>D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. As a trivial example, you can use D3 to generate a basic HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction.

… then you should be pretty excited about d3 right about now. Even if you don’t grok the language, [the examples][ex] speak for themselves.
