This chapter deals with the orbit diagram. This image is one of the most instructive and intricate images in all of dynamical systems. The orbit diagram appears to be self-similar: when certain portions of the picture are magnified, the resulting image bears a striking resemblance to the original figure. Of course, the words “striking resemblance” in this observation are not very precise in a mathematical sense. The curves connecting what appear to be periodic orbits are continuous as c varies—these curves never suddenly jump indicating the co-existence of another attracting cycle. That is, for each c-value, it appears that there is at most one attracting cycle. There is a large proportion of c-values for which the orbit of 0 does not seem to settle down on an attracting cycle.
