title: Moving shapes in JavaFX canvas
body: <p>I would like to know if it's possible to use the GraphicsContext of a Canvas to create a circle(or any shape created with GraphicsContext) and then move it around on the canvas. If it is, what's the algorithm for doing so? I'm used to working with Java and I just can't figure it out.</p>
  
  <p>Thanks in advance for any help.</p>
