Lissajous figure

You will enjoy looking at the beautiful Lissajous figure in the Sunday NYTimes, and particularly at the interactive graph. Scientists have been using such graphs for a long time - Lissajous figures are beloved of electrical engineers, specially sophomores learning to use the oscilloscope. Using them to display economic data to the public is a significant contribution. Congratulations to Amanda Cox of the Times for bringing the science of economics forward to the 19th - arguably even the 20th - century!
