What is the purpose of using Randomizer.nextInt() in the drawCircle function?

Using Randomizer.nextInt() in the drawCircle function serves the purpose of generating random numbers, which are essential for determining both the position and size of the circles that are drawn. By utilizing this method, each time a circle is drawn, it can appear in a different location on the canvas or have a varying radius, thereby introducing unpredictability and variety in the visual output. This element of randomness enhances the visual interest of the animation or game by creating dynamic and diverse designs, as opposed to fixed sizes or positions that would limit creativity and engagement.
