ng? Let's change the dot to a <code>Circle</code>.</p>
<pre><code class="language-javascript">var dot = new Circle( 250, 250 ).setRadius( 50 );

var bot = {
    animate: function( time, fs, context ) {
        form.fill( &quot;#5AF&quot; ).stroke( false );
        form.circle( dot );
    }
};
</code></pre>

<p>As you can see, everything is almost the same, except the dot is now a circle with 50px radius. And we apply Form's <code>fill()</code> and <code>stroke()</code> functions to color the circle blue wit
