That would be great, thanks. I suspected they were using d3, but based on how consistent some of their visualizations are with each other I suspect they have an in house library that they are using as well. Would be cool to hear from the source :)
JQuery Cycle is used for the IE<9 version, which is a slideshow of screenshots taken from the piece. Everything else is done with d3 and jquery as mentioned. We have a custom framework for these dataview pieces, all other work is just based on the same style guide. As seen here: http://www.bloomberg.com/visual-data/
