Let's make a face with D3.js!
This example uses D3.js to draw a simple cartoon face in an SVG canvas. It first creates a large yellow circle for the head, then positions two smaller circles as eyes, and finally adds a line for the mouth. The code relies on D3.js version 5 and directly appends SVG shapes using methods like `svg.append('circle')` and `svg.append('line')`, with attributes set via `.attr()`. Dimensions are derived from the SVG element's width and height attributes.
