Crossings in knot diagram
Hi! Given a plot of a knot, I was wondering if it is possible to obtain the position (within the plot) of its crossings, in order to then add some decorations to the diagram.

I am also wondering if this is possible. It is not clear how, or if, the knot,link diagram plot can be labeled in some way. It would be very useful since you can access gauss code and other ways of describing the knots, how can we label the crossings with the information in those codes?
