I recently have [implemented](https://github.com/micycle1/PGS/blob/dev/src/main/java/micycle/pgs/commons/TangencyPack.java) another type of circle packing. This algorithm takes in a graph which specifies a desired pattern of circle tangencies and searches for an arrangement of circle positions and radii which satisfy that pattern.

It will be included in the next release of [Processing Geometry Suite](https://discourse.processing.org/t/processing-geometry-suite/29924).

These illustrations are from playing around with the complex numbers used to layout the circles…
