This example draws a cartoon face using D3.js. The visualization constructs facial features—including the head, eyes, eyebrows, nose, mouth, ears, hair, and teeth—as individual SVG shapes. The code creates these elements by chaining `d3.select` and `.append` calls to add circles, lines, and paths to the SVG canvas, with dimensions controlled via geometry attributes. Styling is applied through a linked stylesheet that positions the features using CSS transforms. The data is hard-coded within the JavaScript, with the SVG output rendered at 400 by 400 pixels.
