Sorting algorithms visualised in form of a spiral, as well as basic sorting rectangle to fill the background.
Uses promises to delay run time, so draw()
can create animation that is humanly visable. Runs both 'draw()' and sorting algorithms asynchronously.

Given an array of inputs arr[n], we will create a spiral using polar equations.
x = ricos(iθ) + c, y = risin(iθ) + c
r = arr[i]
θ = 2π/n
i = current index of the array
c = centered value for corresponding axis
'spiralVal' is randomised value that to get a random design for the spiral. The random value will influence the modulus and arguement of the equation
spiralVal = randomInt(3, 6) * Math.random() + 4;
Coded spiral equation given array of values
let dotsize = 8;
let fracCircle = (2 * pi)/MAX_VALUES;
for(let i = 0; i <= MAX_VALUES; i++){
// Color of each dot, increasing in value
fill(color(values[i]**2 /1000, 100, 100));
let angle = fracCircle * i * spiralVal;
let x = (CENTER_POINT_X)+ (2*values[i]/spiralVal * Math.cos(angle));
let y = (CENTER_POINT_Y + dotsize/2 + 20) + (2*values[i]/spiralVal * Math.sin(angle));
circle(x, y, dotsize);
