绘制k-means聚类图

Question

data = [[4,1,3,4,5,0,9,10][12,3,5,1,4,9,0,9]...] 

N_CLUSTERS = 8

kmeans = KMeans(init='k-means++', n_clusters=N_CLUSTERS, n_init=60)

kmeans.fit(data)

pred_classes = kmeans.predict(data)

数据在1到13之间归一化。如何绘制kmeans聚类？ 我正在尝试按照本教程（右图）http://scikit-learn.org/stable/auto_examples/cluster/plot_kmeans_silhouette_analysis.html 但这个例子仅适用于两个功能，我有8个。
