Data Driven Documents. YES!

Comparing to jQuery, D3.js is...

Read apples vs oranges to find more things to compare.

Both are free! Modified BSD License (3-clause, BSD-new) for D3.js and MIT and GPL for jQuery.

Modules in D3.js

Core, d3.js

Time, d3.time.js

Various date/time calculation and formatting utils. Time scales and intervals.

Layout, d3.layout.js

Various classes to convert data to meaningful numbers for graps. Stack, tree, pie, and others.

Geography, d3.geo.js

GeoJSON parsers and shape drawing utlis. Map projections and specialized scales

Others Are Coming Up!

Geom: Specific layouts for exotic charts;
Chart: Box, bullet, horizon charts (so far)

(feel free to improve them and offer your ideas back to developers)

Don't forget to use in-browser tools to peek behind the curtains.
