Breeze-viz reference

Writing a reference in a programming book is a dangerous exercise: you quickly become out of date. Nevertheless, given the paucity of documentation for breeze-viz, this section becomes more relevant – it is easier to compete against something that does not exist. Take this section with a pinch of salt, and if a command in this section does not work, head over to the source code:

Command	Description
plt += plot(xs, ys)	This plots a series of (xs, ys) values. The xs and ys values must be collection-like objects (Breeze vectors, Scala arrays, or lists, for instance).
plt += scatter(xs, ys, size) plt += scatter(xs, ys, size, color)	This plots a series of (xs, ys) values as a scatter plot. The size argument is an (Int) => Double function mapping the index of a point to its size (in the same units as the x axis). The color argument is an (Int) => java.awt.Paint function mapping from integers to colors. Read the more advanced scatter plots section for further...
