Called directly after setup() and continuously executes the lines
of code contained inside its block until the program is stopped or
noLoop() is called. The draw() function is called
automatically and should never be called explicitly. It should always be
controlled with noLoop(), redraw() and loop().
After noLoop() stops the code in draw() from executing,
redraw() causes the code inside draw() to execute once and
loop() will causes the code inside draw() to execute
continuously again. The number of times draw() executes in each
second may be controlled with frameRate() function.
There can only be one draw() function for each sketch
and draw() must exist if you want the code to run continuously or
to process events such as mousePressed(). Sometimes, you might
have an empty call to draw() in your program as shown in the
