A modular D3.js-based geologic time scale that utilizes data from the Paleobiology Database.
To use, simply include timescale.js and timescale.css in your HTML document, and initialize into the div of your choice with timescale.init("id-of-div").

Transtition animations are now concurrent. Unfortunately because the way the new d3.hierarchy partition function works, "interval_hash" no longer works the same way as in the previous version.
