Printed Page Ch1 Segmenting Customers Using More Than Two Dimensions (p17)
Code sample for elbow and elbow chart image

On page 17, the code to generate the elbow chart includes the line:
points = df.iloc[:, 1:5].values
but the elbow image that is printed uses the previous `points` from the previous section (customers.iloc[:, 3:5]).

The elbow generated from multi dimensions is much more curved, and would help emphasise the point made earlier in the chapter (#5 is much less obvious).

The sample source code is correct (per the code in book). Additionally, the book's subsequent output tables match the code - but clusters 3 and 4 are switched for averages.

The paragraphs following what I would assume is figure 9.4 (figure doesn't appear to be labeled)

Making a prediction for data point -0.5, 0.0 seems like it should be classified as purple.
