+        Click to add more spline nodes. Backspace key deletes them. The red spline is an x-spline, as <a href="http://wiki.povray.org/uploaded/5/5e/LeForgeronXSplines-10.1.1.44.5770.pdf">defined by Blanc & Schlick (1995)</a>. At each node of the x-spline, you can move the slider to alternate between approximating, sharply interpolating or smoothly interpolating at that node. There are also buttons to make the entire x-spline approximating, sharp, or interpolating.

+        The blue spline is the <a href="https://github.com/d3/d3-shape/blob/master/README.md#curves">standard SVG splines</a>, as made available by D3.js. The approximating x-spline is very close to the basis spline and the interpolating x-spline is very close to the cardinal spline, with the added benefit that the x-spline gives a continuum of approximation between basis and cardinal splines.
