Grayscale Population Randomness

Part 1

Our group is interested in the relationship between land use + value, specifically the impact of rezoning on property values. We are still developing our model but our question will likely be: How does zoning impact local property value?

Part 2

Population Grayscale: All kinds of random( )

def setup():
    size(500,500)
def draw():
    populationSize = 150
    numberPeople = round(random(populationSize))
    gridSize = width/random(numberPeople)
    
    stroke(0)
    if mousePressed == True:
        ellipse(mouseX, mouseY, pmouseX, pmouseY)
    
    for row in xrange(numberPeople):
        for column in xrange(numberPeople):
            x = gridSize * row
            y = gridSize * column
            fill(random(0,400))
            ellipse(x,y,10,10)
