Pygmybrowse GBIF classification

Here is a live demo of Pygmybrowse using the Catalogue of Life classification of animals provided by GBIF. It's embedded in this post in an <iframe> tag, so you can play with it. Just click on a node.

Taxa in bold have ten or more children, the numbers of children are displayed in parentheses "()". Each subtree is fetched on the fly from GBIF.

Expand-Ahead: A Space-Filling Strategy for Browsing Trees

For the "to do" list, expand-ahead browsing looks like a useful approach to build upon PygmyBrowse (see my live demo). The approach is described in "Expand-Ahead: A Space-Filling Strategy for Browsing Trees" by McGuffin et al. (doi:10.1109/INFOVIS.2004.21, PDF also here).

There is a video on Ravin Balakrishnan's site, which is an AVI file that I haven't bee able to coerce my Mac into playing, hence I've posted it on YouTube.
