the v2 coordinate measures
What does the v1 coordinate measure?
Consider the variation along direction v among all of the orange points:
What unit vector v minimizes var?
What unit vector v maximizes var?
Solution: v1 is eigenvector of A with largest eigenvalue
v2 is eigenvector of A with smallest eigenvalue
