It's interesting, but the landing page really need a few random examples of the nice graphics before people click the back button. (You must click two times in the list on the right to see a nice graphic.)<p>Compare it with <a href="https://tikz.net/" rel="nofollow noreferrer">https://tikz.net/</a> (We used TikZ in some project to include some simple math graphics (not as nice as the examples in the page). It's nice that you can keep the graphic inside the LaTeX file.)
