Anyone have an easy algorithm for coloring clusters in a nice way? That is, given k clusters, color each centroid and all of it's associated points in such a way that it is visually appealing and avoids, to the extent it can, coloring two unique clusters the same color.
Also, the same goes for laying out n-dimensional vectors in a 2-dimensional way such that one can get a sense of the distances, groupings, etc. and still navigate in decent way. I've got the plumbing in place in the ClusterDumper + Gephi to make this work (and have a lame implementation of both on https://issues.apache.org/jira/browse/MAHOUT-899) but would really like to be able to produce much prettier visualizations out of the box. -------------------------------------------- Grant Ingersoll http://www.lucidimagination.com
