How do I stop making multiple ellipses keep spawning on the canvas?

okay so this is my code so far:

  `diameter = 30`

    def setup():
        size(800,800)
        background(0)


    def draw():
        global diameter

        if diameter <= 100:
            ellipse(random(50,750), random(50,750),diameter,diameter)
            diameter = diameter + 1
        else:
            text("game over",100,100,100)
            return

I'm trying to make one ellipse appear at a random location on canvas, and grow until it's diameter reaches 100, and then the game over text appears. I realize the ellipses keep spawning because draw() is called 30 times per minute, but I don't know how to change my code so the ellipse appears once only at the random location and grows.

nevermind y'all I figured it out. I feel sort of dumb for not realizing this earlier. This is what I did

diameter = 30
x = random(50,750)
y = random(50,750)
def setup():
    size(800,800)
    background(0)

def draw():
    global diameter

    if diameter <= 100:
        ellipse(x,y,diameter,diameter)
        diameter = diameter + 1
    else:
        text("game over",100,100,100)
        return

Oh, I've just finished here as well: =P~

MIN_DIAM, MAX_DIAM = 30, 200

    clear()
    ellipse(x, y, d, d)

    d += 1
    if d > MAX_DIAM:
        noLoop()
        fill(0xffFF0000)
        text('Game Over', 100, 100)


def mousePressed():
    global x, y, d
    x = random(MAX_DIAM, width  - MAX_DIAM)
    y = random(MAX_DIAM, height - MAX_DIAM)
    d = MIN_DIAM

    fill(0xffFFFF00)
    loop()
