This example renders a simple face—a yellow circle with eyes, eyebrows, and an arc-shaped mouth—using D3 v5’s selection and shape APIs (`select`, `arc`). The SVG is sized from the `index.html` markup, and all elements are positioned via explicit transforms and coordinates. The data source is not a dataset but static geometric values defined in the script. Rendering uses SVG primitives (`circle`, `rect`, `path`) with styling from an external stylesheet.
