That's smart - coupling this with the 'min layers' equation could lead to a 100% iterative solution. We could swap this component in and remove the recursive triangle generation :)

As mentioned in the post - deduping is cheap and easy so introducing the third basis vector u3 could potentially be a great move away from the recursive logic that currently plagues the project.

The above is known to be the optimal 2D packing for equal-size circles. If you want to geek out, consider an algorithm for the optimal packing for unequal-size circles. Say, if there is an importance or frequency measure associated with each plotted circle. Now you've got yourself a math problem.
