Hi, I am trying to recreate this recursive circular pattern (via Daniel Shiffman’s book “Learning Processing”). How do I get the recursive pattern to fill the frame of the screen? As you can see, my code doesn’t include the left-hand side which is primarily white/blank.

```auto
void setup(){
  size (800,800);

}

void draw(){
  background(255);
  smooth(8);
  stroke(3);
  noFill();
  drawCircle(width/2, height/2, 400);
}

void drawCircle(float x, float y, float radius){
  ellipse(x,y,radius,radius);
  if(radius > 13){
    drawCircle(x + radius/2, y, radius/2);
    drawCircle(x - radius/2, y, radius/2);
    drawCircle(x, y - radius/2, radius/2);
    drawCircle(x, y - radius/2, radius/2);
    drawCircle(x, y + radius/2, radius/2);
    drawCircle(x, y + radius/2, radius/2);
    drawCircle(x + radius/2, y + radius/2, radius/2);
    drawCircle(x + radius/2, y - radius/2, radius/2);
    
  }
}

```

I figured it out…

```auto
drawCircle(x - radius/2, y + radius/2, radius/2);
drawCircle(x - radius/2, y - radius/2, radius/2); 

```

This code is missing
