Elastic Lists code open-sourced
For those unfamiliar, Elastic Lists builds on the idea of faceted browsing, which lets you sift through data with multiple filters. Think of when you search for an item on Amazon. In the initial results, filters for price, brand, and category rest in the sidebar. Similarly, Elastic Lists lets you browse data on multiple categories, but with more visual cues and animated transitions.
For an example, check out the browser for Nobel winners (above) or one for five years of infosthetics posts (below).
P.S. While we're on the topic, Moritz also open-sourced the code for his Twitter visualization, Revisit.
