Taking advantage of those 1 million rows: Mandelbrot set in Tableau

In April 2013, Tableau Public; the free version of Tableau’s online product extended the limit on datasets from 100k rows to 1 million. It has been 7 months and I was yet to take advantage of it. How about something pretty and draws just as many marks on the screen, like the Mandelbrot set?

I generated the data points using Julia package in R, wrote it to a csv file then imported into Tableau. Tableau extract shrunk the 16 MB CSV to a 1 MB TDE.
