Knotter uses graphs to represent knots. This allows a very quick and intuitive editing of the basic shape of the knot. More fine-tuning is allowed both at the knot level and at a selection level.
Crossings are located at the center of each edge but this can be changed with styling.
The approach used by Knotter is described very well in Celtic Knotwork: The ultimate tutorial.
