Whenever I see a new graph visualization tool, I instantly start dragging the nodes around like a madman to see how well the graph "balances" in the viewport. I soon noticed there was a tutorial was running while I was manipulating the position of the nodes, and regardless of how much stretching and pulling I did to try breaking the tutorial, it worked flawlessly as if I wasn't even touching it. That, I thought, was really awesome. Well done!
