The post https://mattferraro.dev/posts/inverse-of-a-circle hit HN front page a few weeks ago.<p>Anyone here knows which tools the author is using to generate the beautiful diagrams?
Not from the source code, but JSXGraph (<a href="https://jsxgraph.uni-bayreuth.de/wp/index.html" rel="nofollow">https://jsxgraph.uni-bayreuth.de/wp/index.html</a>) is a great tool for this kind of diagrams.
