Replace plt.scatter with plt.path / plt.plot

[kristian-georgiev]

Currently, the path is just scattered points. Following this StackOverflow post should be enough.

It would be nice to also do an additional plt.scatter of the last point only, with a distinct color (e.g red) and a different point indicator (e.g. 'x' instead of a dot) to denote the end of the path.

I think just doing plt.plot and then plotting the last point with scatter plot is enough, no? I think we are ready to close this, unless I am missing something.
