I put together a cool Harmonograph viewer using Tableau Public for their Viz as Art contest. The Viz allows you to adjust all the metrics of a 2 pendulum dual axis Harmonograph. If you get down to it, basically I have Tableau plotting the points of a set of Parametric equations using the Scatter plot features. The only trick was that I needed to De-aggregate the data. The data coming in is simply a list of integers from 0 to 100,000.
