Discrete Fourier Transform
Introduction
Draw your doodle in one stroke and the script will convert it in a set of sinusoids represented on your screen as moving circles. The method used for this transformation is called Discrete Fourier Transform. All credits go to Daniel Shifman. This is an entry for the js1k-2019 competition based on his work explained in this video

index.html is a shim environment provided by the contest organizers.
human-readable/app.js is a place you might want to take a look to understand what's going on in the application.
src/app.js is what was actually developed having in mind further minification. It was automatically minified into dist/app.js by the Gulp plugin.
Finally, submission/app.js is a result of aggressive minification by means of the Closure Compiler and a couple of further tweaks. That's what was submitted to the competition.
