Information Aesthetics tips us off to a great interactive treemap visualization of the huge dataset from the Barcelona Natural Science Museum (which we discussed earlier) from design firm Bestiario.

Beginning with a broad view of all “Animalia”, you can click to zoom in through Phylum, class, and further on down until you find a single organism.  Once you’ve found your one organism, they provide records with maps and links to other databases (including Flickr) for more information.
