WebPrism also can now plot smoothing splines. You decide the degree of smoothness by specifying the number of knots. This example shows splines with 3, 5, and 7 knots. Since the splines were derived for art (computer animation) the choice of how many knots to allow is yours to make artistically. Splines have nothing to do with data analysis.
