Update http://harthur.github.io/clusterfck/

Update http://harthur.github.io/clusterfck/. It's stating to use:

var clusters = clusterfck.hcluster(colors, clusterfck.EUCLIDEAN_DISTANCE, clusterfck.AVERAGE_LINKAGE, threshold);

Instead of:

var tree = clusterfck.hcluster(colors, "euclidean", "single");

Or even better, remove http://harthur.github.io/clusterfck/
