Yes, it's a degree of interest interaction. There have been various attempts to implement this DOI idea since it came out, and I'm pointing to this one as a rather novel implementation, that may overcome some of the usability issues seen with hyperbolic trees, etc.
<br><br>I would definitely test its usability with a taxonomic tree data set and some "normal folk" before advocating it as the ultimate solution for an EOL project. Denise Green and I did these types of usability tests on three interactive tree presentations available in 2005, providing something of a baseline against which this particular interaction style might be judged.
