title: when i run my code, why does the ellipse/circle not show up
body: <pre><code>from math import sin
  from processing import *
  
  X = 30
  Y = 30
  delay = 16
  radius = 30
  
  def setup():
      strokeWeight(10)
      frameRate(20)
      size(500,500)
  
  def sircle():
      global X, Y, radius
      background(100)
      fill(0,121,184)
      stroke(255)
      fc = environment.frameCount
  
      X += (mouse.x-X)/delay;
      Y += (mouse.y-Y)/delay;
  
      radius = radius + sin(fc / 4)
  
  draw = sircle
  run()
  </code></pre>
  <p>for some reason <code>run()</code> only creates the background.
  does anybody know how to call the function for <code>sircle()</code>?</p>
