Add .attr('transform', 'rotate(10)') to box4?

That's true, you could apply the same transform to the box itself. I'll make a note of that!

Robert, I’m confused. Here you do exactly the thing you don’t like, right? How does that solve the issue? Or is it your goal to write a little convenience function?

The goal was mainly the convenience function. I found it annoying to have to redo this sort of logic over and over, so I wanted something to abstract it away. I don't believe there is a way to completely remove this process.
