A function has a jump discontinuity if the left and right-hand limits of the function are not equal. In such cases, points on both sides of the jump are labeled as discontinuous. -Similarly, points are labeled cusp points if the curve changes direction.

We leverage the point type to determine +which points should be linked to yield the appearance of a smooth curve and which points should not be linked but appear as circles (say to represent discontinuities). Curve manipulations are handled by a set of functions that update the curve points based on user input. The point type is assessed based on the type of curve mode that is being manipulated.
