This script generates a chirped signal by summing a series of sine wave and dispersing them in time. The chirped signal is then analyzed by Hilbert transforms which allows one to visualize the linear chirp on the instantaneous frequency spectrum. (see image)

Many thanks to Andrew0090's Octave code at the Wikipedia Chirp animation, and Jurrien's Hilbert transform question at Matlab Answers
