An intuitive feel to this is essential. Is it possible to develop a diagram for it? --prime mover (talk) 20:43, 17 March 2021 (UTC)

It is possible, and the web provides many examples. My question is whether there is a prefered piece of software for producing nice plots? Maybe Geogebra? I mostly use Mathematica, but I am not sure how much time I will to make the graphics look as nice as plots on this site.--Julius (talk) 07:15, 18 March 2021 (UTC)

I've been using GeoGebra since early days when one of the early contributors started using it for Euclid. I understand there are other packages out there, but I just use what I'm used to. --prime mover (talk) 07:25, 18 March 2021 (UTC)
