I have done a clustering in R using the Mclustpackage with a data set with 17 attributes and 2000 observations. the Mclustpackage is using EM algorithm to do the clustering.

Is there any good way to visualize my clustering? My first thought is PCA.

A parallel coordinates plot, coloring by cluster is a common way to see all the dimensions.
