Keyboard Heatmap

This repository contains the sourcecode of my recently released keyboard heatmap. The keyboard heatmap shows the distribution of characters of a text while you're typing. It's using my JavaScript heatmap library (heatmap.js) to make that possible.

Contributions are very welcome!

How to add your own layout
