Typo on page 419

The 4th and the 5th lines of the codes, counting from bottom, are

plt.plot(x[y==0, 0], x[y==0, 1], 'o', alpha=0.75, markersize=10)
plt.plot(x[y==1, 0], x[y==1, 1], '<', alpha=0.75, markersize=10)

However, the resulting figure is a scatter plot. Therefore, the above 'plot' function should be replaced by scatter.

Thanks for suggesting. I agree that plt.scatter is more intuitive here. I think I used plt.plot with the given markers deliberately here though because there was a problem with some function in the scatterplot in this special case. Because usually I prefer plt.scatter as well. Thanks for suggesting though.
