I am trying to draw a picture like this.

here is my code. I just start it.

```
void setup() {
size(800, 800);
noStroke(); //No black outline around the circles
}
void draw() {
final int CIRCLE_SIZE = 20;
final int NUM_CIRCLES = 7;
final float ANGLE = -PI/4;
background(0);
lineOfCircles(mouseX,mouseY,ANGLE,CIRCLE_SIZE,NUM_CIRCLES);
}
void lineOfCircles(float xStart, float yStart, float angle, float size, int numCirc){
}
void drawCircle(float x,float y, float d,float theta, float diam){
for(int i=0;i<NUM_CIRCLES;i++){
circle(x,y,diam);
}
}
float xAtAngle(float xFrom,float dist, float angle){
return xFrom+cos(angle)*dist;
}
float yAtAngle(float yFrom,float dist, float angle){
return yFrom+sin(angle)*dist;
}
```
