This visualization shows how an iteration of order 1 is composed in term of hexagons. In particular, given a hexagon centered in the origin, the 6 surrounding ones are placed using the coordinates calculated in term of their apothem a and radius r.
The coordinates can be calculated once and then reused for each iteration order of the Gosper space filling curve.
