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.

That's rad.

You don't see Venn diagrams used to represent phylogeny too often, but it does seem that they would make better use of space than cladograms, as this demo suggests.
