Building on information presented in A brief overview of the Mandelbrot set, we describe here a basic method for rendering the Mandelbrot set using canvas.
Before presenting an algorithm for drawing the Mandelbrot set, we first create a JavaScript "class" for manipulating complex numbers. As indicated in A brief overview of the Mandelbrot set, the only operations needed are the ability to square, add, and take the absolute value of complex numbers. The Useful complex operations example shows one way of accomplishing this.
