Im wanting software to allow me to plot multiple 2d points (~10-20) on a graph and then it draws a curve through them, eg cardinal spline (but any equation as long as it goes through the points)
Once the points are plotted I can add/subtract drag them around and the curve updates so I can see how the curve looks
i.e. something like a combination of the following 2 pages

ps, online is OK, or freeware
