Subject is the question.
As I see it, it's useful to know MatLab. A simple query with matplotlib
tutorial shows a number of hits. The first, reference to v0.99.a
documentation barely qualifies. Examples galore and a pretty minimal
introduction. In the first 10 or so hits ther's a blog and
the path. Another choice is
to define an arrow and orient it in the direction of the next segment.
An appealing way to do all of this is to pause drawing the next segment.
That way, the dynamics of the path are clearly seen.
