Braille graph

The goal of this project is to enable anyone to create tactile graphs. This code was written by Jonas Voorzanger, a teacher in physics and computer science at Het Amsterdams Lyceum, a high school in Amsterdam. The code was not originally written to share, so please don't expect clean, well documented code.

## How to use the code

1. Copy the files to a local directory
2. Open `BrailleGraph.scad` in the free OpenSCAD software
3. This file (BrailleGraph.scad) includes (`use`) the two other files
4. Edit (or comment out) the functions and run the code
5. Export to .STL and use a 3D printer

Good luck!
