One way to visually understand the
is through a method called renormalization.
The sequence of pictures below shows graphs of L(x) and
To the graphs of L2(x) are attached small squares
with corners at the nonzero fixed point of L(x) and with base length determined
by where a horizontal line from the fixed point next crosses the graph of
These are the trapping squares.
|Graphical iteration takes any point to the
fixed point at x = 0, the fixed point on a corner of the square.

The complete cascade of behaviors of L(x) inside the
unit square is repeated by the portions of L2(x) in each of the two
Similar results hold for all Ln(x). This explains the smaller
copies of the bifurcation diagram in the whole diagram.
