Three letter words

The English language contains aroud 4000 three letter words. In order to visualise all the words. I decided to program a sketch that would calculate the distance to travel with your fingers to type all the words. Here I calculated the distance travelled and time spent on the well known QWERTY keyboard and compared it to the DVORAK. A layout designed by sienctist to type efficiently. And it turns out that DVORAK is indeed the most efficient layout with a 17meter shorter distance compared to QWERTY.
