Suppose I have a D-2 plot produced by Plots.jl, which may display a time series or a mere parabola. Is it possible to connect two points with a straight line by using annotations or any other Plots’ functionality? I am not considering `vline`

or `hline`

, both of which I know how to manipulate. For example, connecting points (1,2) and (3,4).

Of course, I can always edit a posteriori the plot’s pdf file, but this is not the best option, for obvious reasons.

Help would be appreciated.
