Graph layout experiments with Jsviz

Yesterday I found jsviz, a javascript based tree and graph layout classes at http://www.jsviz.org .
While I am quite happy to have the prefuse Java plug-in to display the complex relationships between taxa I always wished to have something php or js based because the prefuse applet is loading quite slow.
The first experiments with jsviz are quite promising! I begun to simply modify the examples from the jsviz blog pages and fed them with XML files generated by TaxonConcept. The results are very impressing, for example the snowflake graph for Archeoglobigerina cretacea just looks beautiful: http://taxonconcept.stratigraphy.net/taxon_jsviz.php?taxid=1861
