The Curve mark enables the end user to use spline curve drawings. The curve is specified by an array of points and tension parameter that affects the degree of the curve's bend. The curve passes smoothly through each point in a given set of points. With this mark, end users can create spline curves with different colors, opacities, widths, and styles (solid, dash, dot, etc.).
