Paths can be curved in a variety of ways. Curved paths follow a route that is based on the position of the constituent vertices (junctions). The curvature options are straight, rounded, curved, or smoothed as illustrated below. Each defines a simple and intuitive variation on the path of the curve, without the need to understand advanced math, splines, or control points.

Straight paths consist of straight lines connecting each vertex.
Rounded paths are straight paths with the corners rounded off for a smooth appearance.
Curved paths follow a route that vears off toward the next vertex before reaching the present vertex.
Smoothed paths are a lot like curved paths except they pass through each vertex and then vear off toward the next.
