Hi @eisman, I'm very interested in your project and I want to develop it further and make it work with the latest D3 version. To be able to do that, I would like to understand your calculation. Could you please explain to me why you need these functions?

rotation
rotatePoint
rotate
unitaryNormalVector
unitaryVector

I see that you use them a lot in the tickRelationshipsOutlines function. What kind of path are you trying to draw each tick?

it's for calculating the relationships, which comprises arrows and captions. Unfortunately I'm not a mathematician, which is why I can't explain how the calculation works. Maybe this will help though:
