Missing code in chapter 11

[Austin Wang]

Hi, below code is from the book but missing in the cell In[17] of ch11.ipynb.

row_clusters = linkage(df.values, method='complete', metric='euclidean')

Thanks for the note, haven't noticed that! Yeah, without that line, the output may be quite misleading since it was supposed to show that the two approaches are equivalent. Just added it! Thanks
