Needed an easy way to create tests for a perf tuning project at work so I hacked up an app to generate functions from hand-drawn graphs. https://t.co/cX6p9bfmHm
The app simply captures points along the drawn bezier path segments and then translates those points to the grid's scale and X & Y axes.

You can then generate code in a few languages that contains the array of points and a fun of X that returns Y via linear interpolation.
