The picture to the left shows points (c,f_{c}^{n}(x)) where n=1...,1000 of
the Logistic map f_{c}(x) = c x (1x) and f^{n}(x) = f (f^{(n1)}(x)).
The color indicates the Lyapunov exponent
L(c) = lim_{n} (1/n) log f'_{c}^{n}(x)  of the orbit.

When you move the mouse over the bifurcation diagram to the left, you change the parameter c
and will see to the right the corresponding cobweb connecting points
(x,0),(x,f_{c}(x)),(f_{c}(x),f_{c}(x)),(f_{c}(x),
(f^{2}_{c}(x)), .., where x is some random point.
