This demo will fill the screen with white, draw a black box on top
and then print Hello World! in the center of the display

This example is for use on (Linux) computers that are using CPython with
Adafruit Blinka to support CircuitPython libraries. CircuitPython does
not support PIL/pillow (python imaging library)!

1. Orientation

p5.js is a JavaScript library created to establish computer literacy in visual arts applications. It abstracts the more complex components of JavaScript to provide a friendlier environment for experimentation.

Integrated Development Environment (IDE)

An Integrated Development Environment, or IDE, is a workspace for prototyping and developing code. p5.js has a browser-based IDE which we will use today, but you may want to look into using p5.js with VSCode or another ID. You can the browser-based one here.
