I want to plot unit vectors whose orientation varies from [-pi, pi]. A reference figure is below.

Any suggestions on how I can get the desired plot?

```julia
using LazySets, Plots

plot(map(p -> LineSegment(zeros(2), p), PolarDirections(16)), lw=2.,
     arrow=:true, markershape=:none, seriestype=:path)
plot!(Ball2(zeros(2), 1.0), alpha=.1, ratio=1.)

```

Of course, you may want to use `Plots` directly; all the keyword arguments used above apply.
