360 = 7!/(2*7)
7! different ways to choose a closed path on the seven nodes. However, it doesn't matter which node you start on, so divide by 7. It also doesn't matter which direction they are chosen in, so divide by 2.
> Curios how its done? We are using paper.js and gatsby.js. Some behind the scenes: http://volligohne.de/projekte/timobecker/. Check out the source code https://github.com/voellig-ohne/timobecker

I can't say that I'm any less impressed that it's "only" 360 drawings :)
