Here is a good project wish list, If anyone wishes to take it forward I would be willing to help mentor.
http://www.graphviz.org/ Check out one of the graphs which i believe is a good way to represent clusters. Creating this graph is as easy was writing cluster output to the graphviz format http://www.bioconductor.org/overview/Screenshots/photoalbum_photo_view?b_start=6 This is an excellent project which allows you to display graphviz in a browser. Maybe we can create a generic webapp from the current taste webapp and add clustering functionality there. http://code.google.com/p/canviz/ Robin
