Visualizations of the Fibonacci recursion
Figure 1 depicts a classical visualization.

We have a spiral arrangement without overlapping squares.
In this figure and also in the following we use a color code according to table 1.

Tab. 1: Color code
In figure 2 we have a linear arrangement.
Fig. 2: Linear arrangement
This can be done also with other polygons. The figure 3 gives a version with regular triangles.

The figure 4 works with regular pentagons.
Fig. 4: Regular pentagons
The ŇrooflineÓ is not straightforward, but interrupted.
Taking a geometric sequence based on the golden section
leads to a proper roofline (Fig. 5). But this is no more a Fibonacci sequence. The difference is visible at the beginning.

Parts of this figure can be used to draw a regular pentagon (Fig. 6).

In the following figures we will work again with the Fibonacci sequence.
The figure 7 uses half hexagons.

In figure 8 half circles.

In figure 9 half circles again, but this time with a golden geometric sequence.
