This example shows a static smiley face built with SVG shapes: a yellow circle for the head, black circles for the eyes, and a curved line for the mouth. The code demonstrates fundamental DOM manipulation by using D3.js v5 selection and append methods to create and position each shape. It draws directly from the index.js file, which uses `select` and `append` to construct elements on an SVG canvas, with coordinates derived from the `width` and `height` attributes. The project is minimal, focusing on basic shape creation rather than interactive or animated behavior.
