Appending the kNN score

Now you've standardized your input features, it's time to create the kNN distance score for the standardized wine data and append it as a new column.

In this exercise, the 5 nearest neighbor distance score is already available in the object wine_nnd. So that the score is easily available for visualization or further analysis, you'll append the score as a new column to the unstandardized data.
